Hello, Ive been getting lots of info from rokslide these last few years and decided to finally make an account. I just recently purchased a Mathews v3x 33 and im not too sure about my arrow setup. my draw length is 31 inches. the arrow build im looking at is a Easton axis 260 spine cut at 31" or align with the riser an ironwill 125 gr 50 gr brass insert a 17 gr collar. i have slight concerns with this setup from what im seeing ill be under spined. i try to be around 12% foc. assuming with that setup my speeds will be right around 274-280 fps. im also considering black eagle rampage. if there's any recommendations let me know! Thank you.
