I think tuning issues are the number one cause of fletching trouble with WB rests ! I haven't had any real trouble with the old or new WB rests !

But I would upgrade to a new B2 anyway if I were you ! They are very accurate and seem to cause no fletching wear ........none for me anyway !

I used feathers with no trouble and now I have been shooting Bohning vanes for 5-6 months ! I do fletch my on arrows and make sure they are glued well........and I add a dab of glue to the front and back of each fletch !

Here is a pic I took a couple of days ago of a 3 arrow group at 70 yrds......with 3 Axis 340's I have been shooting since April (I don't know how many hundreds of shots ) ! You can see that my fletching still look fine ! I'm using a Deluxe QS with the new B2 disk !! Good luck !
