Whitchurch HS looking to put one over city rivals.
Pick of the games in this weekend's Dragons Rugby Trust Schools League Division One fixtures will be the Cardiff derby between Whitchurch HS and St David's Catholic College.
Whitchurch are taking part in the All England Schools Festival at St Joseph's Ipswich on October 14 and will be all out to go into Britain's top 15-a-side tournament unbeaten.
They hope to field centre/wing James Egan and flanker Sam Warburton who last week played for Glamorgan Wanderers against Bridgend in the Principality Premiership game at the Brewery Field.
If Coleg Sir Gar can field a full side and include their Scarlets players they should have a very slight edge over Neath Port Talbot College.
Neath PT will have the advantage of having already played one DRT game - walloping Bassaleg CS 76-10 - and with some terrific new recruits in scrum-half Tavis Knoyle from Ystalyfera and centre Ashley Beck from Dwr Y Felin CS, will be very hard to beat this season.
Cross Keys College are at home to DRT champions Swansea College in what promises to be a very tight match, while there should also be little to choose between Bassaleg CS and Glantaf who last week were well beaten 34-5 by the very strong New Zealand tourists of Lindisfarne College.
Brynteg CS take advantage of a rest day in the DRT league to take on Christ College in a friendly at Brecon.
In the second division Ysgol Llanhari have come in to replace Chepstow CS who lost heavily to Bro Myrddin in the opening game of the season.
Llanhari were originally placed in the first division but controversially withdrew just before the start of the season, coach Iolo Roberts worried at the prospect of taking on the powerful tertiary colleges.
The withdrawal of Chepstow has given Llanhari the opportunity to come back into the Saturday league but now in the second division.
They take over the Chepstow fixture list en bloc and will open with a game against another Welsh language school in Strade from Llanelli.
In the same division, Glan Hafren entertain Cwmcarn HS and Plasmawr are at home to Olchfa CS from Swansea.
Cardiff HS travel to Llandeilo to play Tregib CS and Cowbridge CS will have Lloyd Williams, son of ex- British Lions scrum-half Brynmor Williams, in the number nine shirt at home to Gowerton CS.
Fixtures for October 7 (10.30 am).
