For those who don't know Shaun (I don't either). He got booted from Pennock's forum quite a while ago. I didn't really see the problem as I tend not to get too put out by people pointing out that I don't know wtf I'm doing. But then again it's painfully obvious by my progress.
His posts were always pretty detailed and interesting. As can be seen by the go juice reference in his sig, he likes the performance stuff. I suspect his blunt approach upset some guys at PFF. He calls them how he sees them.......
BTW Shaun, most of us a stumbling amateurs, so be gentle
