Bow: Bear TRX 36" ATA 72 lbs 29 inch draw, AMO rated at 230, IBO 305
Arrow: 30" Terminator Hunter 6075 with 100 grain Steelhead or Spitfire

Just curious, how much do the arrows weigh, ballpark, and roughly how fast should I be

You need to be a little more specific.

What all do you have on the bow string?

I would estimate you in the 260 -265 FPS

and 61 - 64 # KE

Sorry --

On the string, a brass nock, and a string loop, as well as cat whiskers

(designed to be quiet, not fast)

If you have plastic flecthing your arrow is probably close to 450 grains. If you have a peep........258-262 fps and KE 59-63. Just a guess!

Good Luck!
