I fly from a 600 meter strip and used to share hangar space with a Junior. He never seemed to have a problem and later went on to win the Schneider Trophy in it. I flew with him a couple of times and I think there is a little more room in my Airtourer. This has the advantage of being Annex 2, is aerobatic and despite mine only having 115 hp, it got off the strip (solo) in about 250 metres in the very wettest/boggiest part of the Winter. There's one for sale on AFORS at the moment which might be worth a look.
