C903, I think we're close to being on the same page !

I am with you on the broadhead tuning with that type of tear ! But I don't think it has much to do with the rest design in general !

I'm a firm believer in "what works for you" ......so Letub .....go with the QT 800 and don't look back !

What should you do with your WB ??.......get rid of it ! It obviously is not fond of your set up ! I don't think a B2 would make a bit of difference....there is something wrong here but I can't offer much more help without being there.........this is just something I have never seen out of 6 or so bows I have setup with WB rests !! Good Luck !!
