Here is my setup for compound bow....
Mathews z7eXtreme Tactical
28" draw
63 pounds
single pin site
QAD rest
Axiom stab
5 arrow quiver
Most recent arrow was the Carbon Express Pile Driver 350's. I believe these are a shy over 11 grains per inch. Shooting mostly a 125 grain two blade Magnus, sometimes a 125 grain NAP Hellrazor. Why you ask? Because the arrows were on sale for $19.99 per 6, and the broadheads were on sale for around $12 per six on the Magnus and about $18 for a 4 pack of Hellrazors.
Why shoot these? Because I hate losing arrows or breaking arrows when I stick pigs. I don't feel so bad if I don't have $30-$40 per arrow tied up in a pig sticking. And they kill the crap out of deer as well.
Heavy arrow? Yup, but still getting about 275 fps out of my setup. Could I get faster? Probably so, but a lot of people don't understand that to get the top speed out of the bow, as advertised, they will need a long draw length, shoot the lightest arrow possible and have nothing on the string. My bow is rated for 322 fps and I WILL NEVER SEE 322 fps. Why? Because I shoot a 28" draw and have stuff on my strings.
Don't over guess everything. Get a setup, start shooting and enjoy. In my opinion, if I wanted to shoot deer at 50 yards and beyond, I would go to my rife. Bowhunting is a close up game, the closer the better. I believe my longest shot at a deer was 38 yards and the closest was 3 yards from a pop up. Get the deer in close, observe and learn. Nothing like sitting in a stand or pop up and see a fawn start sucking on its mother and when pulls away, a little bit of milk on its mouth.
