New Bow, Which Arrow & Components?

[N2TRKYS]

My old Hoyt set at 70lbs with a 27.5” arrow throws 481 grain arrows 265fps, 430 grainers 275fps, and 406 grainers 288fps.

Hard for me to locate an arrow that comes out at that weight that is also spined correctly with anything over 10% FOC.

A 300 spine arrow around 9 gpi cut about an inch shorter than your draw length should let you get to 450-460 gr total arrow weight with FOC well over 10%. Example: Black Eagle Outlaw 300 (9.1 gpi) cut to 27.5" + 175 gr total point weight + 9 gr nock + three 7 gr vanes = 455 gr TAW and ≈15% FOC.
