I'm actually the opposite, I prefer the BFD over FBV, I found that for me it performs better, and holds an edge much longer (i went 3 months playing 2-3 times a week on my last sharpening). I really gave FBV a try, and tried multiple hollows, and while I found the 90/50 FBV I'm using for the rest of the summer is ok, I still prefer the X8. We can argue about which one is scientifically better, and I'd concede the FBV probably is, ultimately its going to come down to personal preference, and the only way to know is to experiment with different grinds until you find the one that's right for you. Oh, and hope it isn't one where there's only one guy where you live that can do it, and he closes shop for the summer.
