Right now it would have to be the rocky ti100. My reasons are that IMO it has the strongest ferrule out there, the blades are very strong and it is, out of a well tuned bow with a good helical fletch very nearly as accurate as a field point(for me anyway). I would have no reservations using it on any sized game and would not be concerend about it, should it encounter heavy bone. Also as I get older and can't pull as heavy a draw weight I don't need to be concerned about whether I have enough KE for a mechanical.

And that, from a mechanical(Snyper) user. ;-)
