Go to this website and watch the videos. Trust me, it's well worth the time doing that. You'll get an education on why arrow spine is so important for fingers shooters, and you'll be able to see exactly why you're having lousy results with that whisker bisquit.

There is no way the wb or any other full containment rest can allow a fingers released arrow to pass cleanly through it. I knew you'd have difficulties with that thing when I read your first post, but I didn't say anything because I've taken so much flack from wb true believers over the years, each and every time I dared suggest their beloved rest is not appropriate for someone shooting fingers. Now that you've tried it and are ready for some hints, I can point you in the right direction. In my opinion, with a bow that has a mounting hole in the sight window, that direction leads straight to a flipper/plunger combination.

I've shot flipper rests in competition for many years and have tried most of them. My favorite flipper rest -without getting into the high end competition rests like the Olympic shooters use- is the Cavalier FreeFlyte Micro.

Micro adjustable for windage. The flipper is magnetically operated instead of spring driven. No springs to wear out and break, or make a deer spooking SPROI-OI-OING! when you release. It has a steel sideplate that will protect the button on your cushion plunger from wearing out (carbon arrows eat those buttons alive, if they're not protected). Just adjust the centershot as usual, then run the cushion plunger out to lightly touch the back side of the side plate. Then you fine tune the plunger pressure to perfectly match your arrow spine.

When you get it set up and dialed in, the rest will be a lot more consistent than you can shoot, I guarantee ya.
