Dixon, I had the same issues with the WB, but I think you have some centershot problem or your vanes are hitting something they shouldn't.
Can you follow the arrow out of the bow, do they fly straight and do they hit the target in a 90 degree angle. The best way is to use a good glue, like goattuf and just clean your shaft with alcohol and not the vanes. Just use enough glue as neccesary and be patient, don't try and glue them on to fast. a drop of glue at the back and on the front of the vane helps allso.
I have had problems finding centershot with a WB, even after walk back tuning.
I bought this Easy Eye laser tuner and that does the same thing but in minutes.
Don't give up on the WB yet, it's one of the best rests out there, it's simple and effective and shoots great once it's mounted on perfect......
