That's incredibly powerful and efficient, very effective for hunting I imagine. However with such high velocities and Theraband Black won't longevity be a problem?

I decided to settle for a compromise for my hunting, any more and I find it unwieldy, especially when shooting at targets which are elevated... I plan to use Tex's Express Bands, so I'm expecting to easily kill pigeons and squirrels from up to 15m using 0.44 lead!Depends on your strength. 40" is not a lot in comparison with butterfly like draws. 75 to 80 m/s is doable.
