volsfan, how do you have yours layed out? What kind of reaction do you get from it? What kind of condition are you throwing it on?
I'm the exact opposite with my WMB, it has actually gotten stronger over time for me. At first when I bought it, I thought it was a dud. I plugged it and re-drilled it properly... I still didn't like it, but I kept throwing it. Out of the blue, this monster came alive. It needs to be cleaned all the time, that's the key!
