If you can afford it I would go with a couple different broadheads. For turkey, I will go with a LARGE mechanical cut like the grim reaper whitetail specials or RAGE 2+inchers. For Deer you can use your T3 mechanicals just fine or you could use the two I mentioned above. Depending on what type bear you are hunting and how large, I might suggest a fixed blade over mechanical...if you hit bone or if it is a LARGE bear you will want something with major penetration and bone crushing power. Maybe something with a trocar tip as well.
