with feathers i dont loose any with vanes i loose1-3 but never anymore. i shoot 50 yrds with one pin (dead on from 10-40) with my WB, i love it. it was nice to see a guy the other day on a hunting show using a drop away and totally missed a doe by about 5 feet then he looked down and noticed his rest was messed up. put the WB on tighten it down and never worry about it again.
