But I am getting wrinkling or marks on the fletches that I don't get with 4" easton vanes.
That's just cause they are quick spins.
I tried them in the past and would see wrinkle marks just from the arrows impacting with a 3D target. I was shooting a drop away rest and there was no contact at all.
In my findings the QS vanes are one of the least durable vnes on the market.
If the vanes are making contact with the rest you should have seen the same marks on any other vane you used.
Edit........this was with the standard 4" quick spin vanes.
