I used Radial X-weaves for two seasons. Only issue I had with them (compared to my a/c/c's) is that they are "brittle". I broke more arrows in one season of shooting them than I thought I should have. Last year I killed more deer and only had one arrow be destroyed. If I look at the big picture.....the a/c/c's are worth the extra $$.
But...I had no performance "issues" (other than the one, noted) with the arrows. My son still shoots them.
Good luck
