RE: need info on arrows
Bgfisher is right. Depending on your arrow length and draw weight, this will tell you the correct spine for any given manufacturer.
I shoot the same exact setup on my Bowtech. I use Gold Tip arrows and probably won't be switching any time soon. I tried a lot of different arrows and nothing has held up to the abuse or shot as well as they have for me.
IF you were to choose Gold Tips and your arrow is 27-28" long, I"d say the 5575 spine would tune well on your bow.
