RE: BroadHeads... Fixed or mechanical?
Depending upon your arrow weight, you should have enough energy to use Mech heads on game such as deer or even some larger game, as long as itswithin reasonable shot distances.
However, fixed blades get a bad wrap. A well-tuned bow can spit them out with Field Point accuracy. Dontoverlook fixed blades. Many quality ones on the market.
Sorry this is so short, butthere are lots of threads about this, and if you doa search,Im pretty sure you could find moundsof more info about this.
Good luck---Matt
