I tried out some WWs with the tip severly pyramided on some bunny's at TX Sweat earlier this year, and they did real well....although I was really after hogs and javies...I didn't really go after bunnys.
So I used them again during the Littlefeather Bunny hunt last month...and I was really after bunnies so the heads got a LOT of use.
They performed very well...often pinning them to the ground, prickly pears, or mesquite trunks. Very consistant hit-recovery ratio. Best I've found OR seen for bunnys.
However, I did see room for improvement in getting them out of the back quiver....they tended to drag a bit. So I took them to the belt sander and backed them up at the turn using the guard as a jig and took off the sharp corner and flat spotted it. Made a big difference....now they just glide out.
