I'm also interested in trying out lead. I personally love the headlight balance and that's the main reason I got this stick. I used to play with the Pro Staff 7.5 (12 points HL) and this frame was the closest to that I could find. If I remember correctly, that Pro Staff was pretty picky about tension too.
blackdot: if you try some lead, can you post back here? I'm off to the local shop to pick up some Unique lead tape. I decided to go with this brand because they cut in 1/4" width. Babolat lead tape cuts in 1/2" width or 1" which is too fat for this stick. I'll post back after Sunday with my experience.
