i used boosters about 3 times. Twice I got investigated by the WCAA and the kids didn't sign, once I was successful. The time I was successful, it was with a juco, and the AD said something like "well I hope he works out, that kid is a nut" after I signed him. I don't know if that meant anything or not. But I am guessing there is something in the personality that tells you whether a kid will be the right kind to use boosters with. I haven't used it in about 8 seasons, though, because 1) my experience was that it is rarely successful, 2) you don't seem to really need it to get good recruits, 3) the reputation hit can be pretty hard to shake
