I've been using Head blade products since the very beginning. Received my first kit as a gift (don't even remember from who), and been using them since. I've tried them all, limited editions, etcetera. When they pulled them off the retail shelves I drove all over town and purchased all HB3s and Sport models I could get my hands on! For me, the Sport with HB3 is best combination, my problem with the Sport is always the finger grip breaks. I opened my last package of HB3s a couple of weeks ago, and every Sport that I have left has the finger grip broke/repaired. I'm glad to see I can replenish my inventory of Sports, even if it means I'll be downgrading to the HB2s.
