Having went through this very process last season, I can attest that bare shaft tuning is the way to go. The flipper rest w/ cushion plunger is certainly the "standard" (tried and true) rest when shooting fingers. I personally shoot a WB as do several of my hunting partners with no problems. At first I was a little skeptical that the WB would work with fingers, but after seeing a few friends shooting tight groups with fixed bladed heads out to 40 yds, it convinced me real quick!

I made the switch and haven't looked back. I'm loving it!
Don't get discouraged when you first start shooting large groups with fingers. It does take a while to master the technique of releasing the string and getting a consistently smooth release. At least it did for me. I would suggest using either a glove or tab when you first start. It does aid in a slick release. Just my $.02.
