I fly both types and I reckon(with my mere 100hrs) that the hershey bar wing flys much better-the warrior seems a bit lethargic in comparison and pretty idiot proof at the stall,just mushing around.
As my first instructor said,"its like the difference between an old sports car and a modern saloon,the saloon will look after you some more but the sporty model is always more fun!"
The 140 we have however is old school, and the trimmer/plunger throttle etc combo is a bit sh1t!
