Interesting that Adam. Was it the complexity that made it difficult or the speed? I'm OK with a bit faster, I reckon I could cope with 140 knots or so, we have a 172 that cruises at around 110-115 knots and TBH I can't tell the difference between that and our 152 which plods along at about 85, but I'm not sure about all the extra knobs and stuff like cowl flaps, CS props, landing gear etc.
