Training in Scottish Central belt
Might also be worth considering Kingsfield Helicopters based in Perth.
It is true that the R22 needs quick reactions and can be a bit twitchy but the old adage that if you can fly a '22' you can fly anything still holds good. The '22' teaches you enormous respect for helicopters. Complacency will kill you, no matter what type you fly. You can always take the money you will save and put it towards a better '44' when you are done.
I have flown with Scotia and HJS so PM me if you would like any more information.
