For all-out balls-to-the-wall 3D in that size range, the best option is a profile. If it has to be an ARF, I'd go for the Chinn Yak or perhaps the OMP Edge. The Edge is more docile and designed to be a 3D trainer. The Yak is arguably the most capable 40-size profile ship on the planet right now, but with mild throws and appropriate CG, it should be mild enough for anyone who has progressed beyond a typical low-wing sport ship.

If you're not interested in a profile, you can just ignore me.
