Timba,
At your draw weight and length IMO you are going to have a near impossible time trying to find ONE arrow that will do both..........At 53# you could easily shoot a 265-270gr arrow for 3D and get all the speed you want (especially if you lose the silencers which aren' t needed for foam targets) But should you shoot that light of an arrow at deer? I would say probably not.
A heavier 400ish grain arrow will be good for deer but is gonna fall short in the speed department for serious 3D shooting.
You are going to run into this problem with your specs with basically any bow out there........even one as fast as the VFT.
The BKII OptionII as Jeff pointed out has basically the same brace height as the VFT but will pick you up another 10-15fps or so right out of the box at your specs.
That would be a better double duty bow for you than the VFT in my opinion......a bit more ATA length (36" ) and some additional power would help you a heck of a lot more than someone like me who is already drawing 30" and can shoot 70#+.

I think in your case what' s good for one application won' t be good for the other, so my suggestion is if you must have one bow and want to COMPETE in 3D , then get 2 completely different sets of arrows.............if on the other hand you want the bow mostly for hunting and shoot 3D for hunting practice and fun, one moderately weighted set of arrows would be appropriate.
