You asked for opinions on what's THE BEST fingers rest. IMO, the WB isn't even a
decent fingers rest. I've heard a few guys say they work for fingers but I remain strongly unconvinced. I won't go into the details because you can't honestly discuss the wb without being accused of bashing.
It's darn hard to beat a flipper rest as top dog for fingers. I used the Cavalier FreeFlyte Micro for several years. Golden Key Futura is another besides Cavalierthat keeps a good selection of fingers rests in their inventory. They've got several excellent flipper rests.
They also still have some other old standbys, like the Star Hunter, Hunmaster Supreme, even several varieties of springie rests. I am a big fan of the springie also. It'san excellent fingers rest, but only if you shoot feathers.
