However, he is still keen to go into the Ranfurly Shield encounter without introducing any new "imports" into his team, and is optimistic that form shown in tomorrow night's game, which will probably be played in four quarters, will enable him and assistant coach Wayne Roache to continue with those plans.
"We'll probably give 26 to 28 players a decent run and it's over to them to show they can do a decent job for us. That's why it's a trial more than anything else."
Just who will be part of the starting line-up for the Wanganui match had not been finalised at the time these notes were penned but Syms suggested several players could be seen in positions different from what they have been playing at club level, especially in the backs.
They could include Corey McFadzean, usually at first-five for Carterton but probably more likely to be at fullback or wing for Wairarapa-Bush and Nick Olson, who has been in midfield for Greytown but is more likely to also be at either wing or fullback for the rep team.
Martinborough first-five Tim Priest, who was such a success story for West Coast in the Heartland championship last year, missed the Wellington XV match through injury but is expected to have at least 40 minutes' action tomorrow night.
Who will captain the team is still to be decided. Carterton loosie Johnie McFadzean had that responsibility against Wellington and delighted Syms with the way he responded and another couple of players will probably have the chance to push their leadership credentials tomorrow night, one of whom is likely to be Greytown prop Kurt Simmonds who filled the role in 2013. He missed last season's campaign through injury but has been in fine form on the club scene this year.
