Pro Mark 747 rock - apparently the same as Neil Peart, but that's nothing to do with the reason I use them. I've always been a big hitter and spent years searching for a tough stick that felt nice. By a process of elimination I found 747s.

I did have some Dave Lombardo 2B (Pro Mark) signature sticks a while ago which felt nice, but they broke after a month's hard labour. Oh well.
