Do Quick Spins really make a difference? I've heard they make your groups tighter, and they are more accurate. Is all of this true?

I tried the quikspins earlier before the season started. I did see tighter and more consistent groupings, but not that dramatic. However, they were noisy, slow and not durable. For the cost of these over - priced things I really did not find it very cost efficient. I then switched to the blazer vanes and prefer them much more. They are consistent, durable, and fast.

I found them to be too heavy and not durable at all. Do a search on here and you will get lots of info both ways on these.

I for one love these vanes. Everybody says they are heavy...yes they are a little heavier, but I did not have to re-adjust any of my sites. Everything stayed right where it was with my old vanes. So the weight does not cause to much difference. But what it did do was take my tuned bow shooting great groups and make the groups even better. These vanes will not take a poorly tuned bow and make it shoot awesome groups.

As far as the durability. I have shot them for the last 3 months and have only replace 5 vanes. 3 of the 5 was because they passed through my target and put a wave in them. I would have had to replace my old ones too, so I call that a wash. 1 of them was at a bow shoot and my buddy decided he like where my arrow was and shot for my nock. Well he missed my nock but pierced my vane. No control there. The last one was when I was shooting groups for the first time and I started rubbing arrows. That one was stupid and my fault. If you start stacking arrows in a target you have to expect to ruin an arrow or some fletchings.

Blazer vanes. We sell a ton of them at the shop. They will come off the arrow before they will tear it seems. Small and tough just like my women.
