Just got a bow off my buddy (dannybows) it's a howatt high speed 58'50#@28 now what spine carbon arrow do u recommend w how much weight upfront would you say would be best! Ps Danny love the bow bro!

I'm going to guess around .500 but you didn't say your draw length, or if is cut to center. 3Rivers Archery has a pretty easy to use (and free) arrow calculator. I think Stu helped design it. It'll allow you to get a baseline of different options. It will get you very close and your form and other personal factors associated with the bow and the shooter can be fine tuned with slight tip weight changes, strike plate build-out, and brace height. Just an option. You're likely to get several different answers.

Of you're going to cut the shafts I would go with a  500 and get points from 125-200 and see what flies best

35/55 with 145 up front try her out. 15/ 35's as well and 2016 with 145 up front and of coarse woodys.

I draw to 29in

Rymancat is about spot on from the looks of it and I would play with point weight

I am partial to the arrow dynamics shafts and would be inclined to recommend the Trad light, just leave it long.

Full length Beman Centershot 400's with a 50g insert and 125g head will do ya.
