Coach: Eddie O'Sullivan.
In: P Lynch (scrum-half, St Mary's), G Kelly (prop, DLSP), E Molloy (centre, Galwegians), A Pearson (centre, Mullingar), M McConnell (lock, New Zealand).
Out: D Neary (wing, Creggs), J Murray (centre, Creggs), K Slevin (centre, retired).
Prospects: A big pack will be strong in the setpieces and could grind opposition teams into the ground. Mid-table.
Bective Rangers
Captain: John Carvill.
Coach: Harry Williams.
In: D Wall (wing, St Mary's), A McClean (wing, Greystones), R McDonnell (centre, UCD), M Edwards (scrum-half, Dublin University), B Cunningham (out-half, Dublin University), B Masoe (back-row, New Zealand), D Assenheim (full-back, Ausstralia), P Comerford (centre, rugby league), M Garford (lock, Seapoint).
Out: J Hannon (Monkstown), S Wilson (Old Wesley), A Johnston (wing, Old Wesley), V Cunningham (out-half/centre, Wanderers), C Whelan (full-back, Lansdowne), A Gillen (wing, St Mary's).
Prospects: Have lost the fulcrum of last season's team, and that's just Trevor Brennan. Mid-table.
City of Derry
Captain: Neil Stewart.
Coach: Gerald McCarter.
In: E Martin (out-half, New Zealand), A Irwin (back-row, NIFC), K Baldrick, OLaverty, R Millar.
Out: K Gallick (number eight, Ballymena).
Prospects: Already lacking in real power up front, they have now lost an aggressive cutting edge in Gallick. Relegation candidates.
DLSP
Captain: Ronan Garvey.
Coach: Philip Werahiko.
In: D McCabe, S Tighe, M Sheehy, R Buckley (all Old Belvedere), F Fitzpatrick (Blackrock), C O'Molloy (Dundalk).
Out: G Kelly (prop, Buccaneers).
Prospects: Always competitive, well-organised side who won't roll over and have their bellies tickled by anyone. Mid-table.
Galwegians
Captain: Barry Gavin.
Coaches: Joe Healy, Bart Fannin.
In: W Ruane (full-back, Ballina), J Fallon (full-back, Corinthians), N Carolan (wing, Corinthians), A Reddan (centre, Lansdowne), E Elwood (out-half, Lansdowne), M Finlay (prop, Wanderers), D Little (prop, returns from NZ), J Charlie (flanker, New Zealand).
Out: A Connolly (full-back, Australia), E Molloy (centre, Buccaneers), K Barrett (out-half, Old Crescnt), I Plaice (scrum-half, Corinthians).
Prospects: Serious recruitment drive means they could field 10 Connacht players. Can maintain form over long season with Elwood a class act. Champions in the making.
Greystones
Captain: Marc Evans.
Coach: Ciaran Fitzgerald.
In: M Wyse (out-half, Wanderers), T Curtis (lock, New Zealand).
Out: A Dignam (back-row, Clontarf), A McLeane (wing, Bective), R Vance (centre, Monkstown), R Murphy (outhalf, Clontarf).
Prospects: Neither of the Murphys, cornerstones both, seem to have been replaced. Mid-table.
Instonians
Captain: Kevin McKee.
Coach: Brian McLaughlin.
In: G Cornelius (scrum-half, New Zealand), P Russell (outhalf, previously retired), G McCausland (wing, previously retired).
Out: I Gray (wing, Ballymena), R West (lock, Ballymena), N Moffett (wing, Dungannon).
Prospects: Not great judging by opening defeat to Old Wesley. Another relegation campaign.
Malone
Captain: Stuart Duncan.
Coaches: Mark Reynolds, Paul Andrews.
In: P Hunter (back-row, Regent House), R Eadie (lock, Donaghadee), L Kerr (Belfast Royal Academy), S Elliot (Grosvenor), I Coulter (London Irish).
Out: W Harbinson (centre, Dungannon), S Willis (centre, Dungannon).
Prospects: Have lost a club standard bearer in the useful Harbinson. Mid-table.
Monkstown
Captain: Hugh Maguire.
Coach: Andrew McMaster.
In: R Vance (centre, Greystones), J Hannon (BR), R Cleary (wing, Lansdowne), B Whelan (Cork Con), W Healy (Highfield), S Brady (Greystones), D Boundy (Sunday's Well), P O'Hanlon (Sunday's Well), B Harrey (Athy).
Out: D Cole (Old Wesley), H McMahon (UCD), J Collins (Old Crescent), B Corrigan (Co Carlow).
Prospects: Usually well organised with a good pack in all departments and sound at half-back. Midtable.
Old Wesley
Captain: Rory Moloney.
Coaches: Noel O'Dea, Ciaran Callan.
In: S Wilson (wing, Bective), A Johnston (wing, Bective), P Allen (out-half, Old Belvedere), D Cole (prop, Monkstown), M O'Driscoll (back-row, Wanderers), R Gavin (back-row, Richmond), J Nowlan (lock, Australia), R Duggan (hooker, Naas), R Breen (wing, Kilkenny).
Out: A Hawe (Athy), R Browne (Old Belvedere), B Casey (Lansdowne), M Higginson (NIFC), N Gibney (UCD), G Walsh (Dublin University), J Feehan (retired), C Pim (retired).
Prospects: Face difficult transitional period. Two points against Instonians was encouraging but could find themselves in bottom half.
Skerries
Captain: Billy Mulcahy.
Coach: Shay McGuinness, (backs Willie Dawson).
In: D Connolly (centre, Blackrock), J Reilly (scrum-half, North Kildare), A O'Sullivan (scrum-half, Lansdowne), B O'Sullivan (flanker, Lansdowne), D O'Sullivan (full-back, Lansdowne), B Higgins (lock, returns from USA), C Chamber- lain (full-back, New Zealand).
Out: J McCabe (scrum-half, Dundalk), O Ennis (prop, Lansdowne), R Davis (Malahide), D O'Connor (Balbriggan).
Prospects: Least heralded of upwardly mobile northsiders, last season nearly making it three promotions in a row from fourth division. Would be happy to emulate last season's fourth place.
Sunday's Well
Captain: Richie Daly.
Coach: Murray Kidd.
In: V Nelson (hooker, Highfield), M Kenworthy (full-back, New Zealand), N Murphy (lock, Old Belvedere).
Out: J Lacey (wing, Shannon), L Murphy (centre, Highfield), J O'Connell (Young Munster).
Prospects: Very keen, very fit and very organised. Despite losing Lacey's finishing pace, they have a good, potent back line. Dark horses for the play-off.
UCC
Captain: Aidan McSweeney.
Coach: Peter Melia.
In: R Collins (wing, Cork Con), R O'Donovan (centre, Cork Con).
Out: J O'Mahony (out-half, Dolphin), D Keeshan (wing, Dolphin), F Sheehan (hooker, Cork Con), J Kelly (Cork Con), J O'Driscoll (prop, Cork Con), J Kiernan (wing, Cork Con), C Kehilly (back-row, Cork Con).
Prospects: Relegation threatens, though they could rally late on.
Wanderers
Captain: Shane McEntee.
Coaches: Glynn Davies, (assistant Ian Counihan).
In: A Rolland (scrum-half, Moseley), V Cunningham (centre, Bective), P Divich (full-back, Lansdowne), R Corrigan (centre, Lansdowne), E Olazabal (out-half, France), T Walsh (prop, Shannon).
Out: D Coen (prop, St Mary's), M Finlay (prop, Galwegians), M O'Driscoll (back-row, Old Wesley), M Wyse (outhalf, Greystones), J Carroll (wing, Old Wesley), O Cobbe (outhalf, Blackrock).
Prospects: Heavy recruitment drive signals renewed intent and promises expansive game with good loose forwards, intriguing Basque out-half and Welsh coach. Mid-table.
