I also agree with Leinsg91...it's more about weight (and shot placement), than speed.
Frankly, I see a lot of TV guys not getting a pass through with their compounds and I'm guessing it's because they're shooting very light arrows in order to flatten their trajectory.
You'll see that many trad guys use point weights that can meet or exceed 160+ grains--I've got 225 up front and total arrow weight is 500 grains out of a 46 lb recurve. This gives me added kinetic energy, especially at longer distances.
Likewise, like Tracy is pointing out, mechanicals are generally frowned upon by traditional shooters--they rob you of too much KE.
You need a heavy, cut-on-contact, fixed blade broadhead at the business end of a heavy, properly tuned arrow, being shot at game taking into account all ethical decisions, i.e. know the limitations of you and your equipment under specific circumstances.
I shoot the Magnus Snuffer SS and generally get full pass-thru's. When taking on hogs, I'll switch to the 2-blade Stinger with bleeders to combat their thick hides.
Above all, like Leinsg91 stated, enjoy this journey my friend! You won't be disappointed!
