I think things do need mixing up a bit against Bath. The 1st/2nd team approach was well suited to our first run of 3 games, allowing us to target Saints and Sale and trust in a weaker side against Worcester. Next 4 are all strong opponents and apart from trying to second guess what sort of side each will put out, we can't put a side out against each of those that will be capable of beating their first choice 23 more often than not.
There were some reliable, experienced heads in the Worcester starting XV that would be far from out of place in Wasps' first team, the likes of Miller, Gaskell, Lima, McIntyre, Watson could all rotate without too much of a drop off, plus emerging players like Oghre, Barbeary, Vellacott, T Willis. Shame we couldn't retain Ash on an extended contract for the rest of the season as he would give us a bit more depth of experience.
