I'm not Mr High End, I like to kill deer and go to a few 3d shoots in the off season. I won't buck up for the .001s, I'm not a good enough shot for that to matter. The .003s are just fine with me. And the .006s are probably good enough, I shot them for years. I've never got away from the standard diameter, they work for what I do. On brands, I've had some carbon express that I liked ok, the old ones were terminator selects. I think the last ones were called mayhems--pretty sure the same arrow, just a new name. Always kind of partial to gold tip hunter xt's, they seem very tough--altho I have had a few of them that didn't fly the very best. Have some eastons I like fine too, they shoot good but to me they seem to break or the inserts push back up in them easier than gold tips. Got some victory's last fall and altho I haven't had them as long as the other brands, I'm not sure but what I like them the best of any I've ever had. Scheel's sells them, calls them 'Vendetta's. Had'em on sale last fall for $35/half dozen. I'll be getting more of them at some point--even tho I don't really need more arrows. A guy on youtube did a bunch of fairly scientific tests on various kinds of arrows and victory's came up pretty big. Samuel White, I think? I thought it was pretty informative. After seeing that, when I saw them for $6 apiece I had to try them. Grabbed some for a buddy too, and he likes them a lot too.
Dont know if that really helped...
