johnhardy1,

The more more rounded LE of the airfoil in the tip makes the root of the wing to stall first, the roll rate of this big constant chord (1000 sq in) wings is pretty slow either for pattern flying (45 deg), and the weight difference is about 500 gr !! (WS 20-25% lighter).
For me it is ideal to have a plane that can do estable elevators, harriers AND snaps, this is a very dificult combination in the design... try to do a blender with a diablotin... not pretty, but stalled flight is optimal; itīs all compromise
