I think Matt/Danny's preferred 1-7 would have Zach (4.92) at reserve - although they also said that may be unrealistic.
As for Rew, he is going to be based in Leszno Poland and therefore flying in for any UK meetings. Ippo with Doyley makes sense being close to Stanstead as would any track close to a decent airport and flights - but he will still need machinery, transport, mechanic and workshop facility wherever else he goes.
