RE: Profile
Um, choices are not that difficult if you are limited to ARF:
Morris: Top Cap, Sudakhoi, Knife
Extreme Flight: Profile Edge
Goldberg: Extreme Edge 540
If you want durable one, Goldberg Extreme 540 should last just as long as your Extreme 330, if not longer, due to its sheeted control surfaces. Extreme Flight Edge "appears" to be built light, so it should be the best performer.
