Thanks for replies.
Those shots at 25 yards would be missing reducers if we have them at that angle up trees (and you aim dead on)- could be interesting if they are like that in the GPs - with wobbles and all.
I remember, a downhill shot (standing) in a GP last year. - think it was Anston - about 15 yards and very steep angle downwards (standing on a pallet) - where should I have aimed? Still think about missing that one!
