The Something Extra is NOT a 3D plane, even with tail mods. I tried modifying the tail and it didn't work. The funky is only a little better. If you want it in the .40 size AND you want good 3D with a .46, you will end up with a modern profile at around 4 lbs. At about 4.5- 5 lbs, you will loose adequate 3D power with a .46. My suggestion is the Chin Yak, MOJO, EF-edge, Bad boy, or the OMP- edge/yak.
