I was thinking of trying the goldtip arrows out and it seems like alot of poeple really like them. I shoot carbon express 3d selects now, I like them alot, but am just in the mood to try something different. Can someone tell me what size I would need. I will be shooting a hoyt cam 1/2, 29 inch draw with string loop, 65-67 pounds, and 100 grain heads. I will use them for hunting. Can you use the easton nocks on these or do you have to use a goldtip nock? My 3d selects finished weigh 396 grains, and I would like to stay in that range or right around 400 grains. I try to stay around 6 grains per pound. I would like to use the black shafts and was wondering what style to use to get me what I am after? I remember reading when these arrows first came out, that they had an abrasion problem and were hard on rest silencers due to a rough surface. Is this still an issue? Give me some feedback on these arrows, and let me know if they are worth trying, or if I should just stick with what I have. Thanks.
