I dunno, I reckon the depth of those teeth will be fine. We'd naturally assume that the bigger the teeth, the better the engagement. But to compare, Drumroll II has quite big teeth and Galactus/Touro Feather have quite shallow teeth (like Dave's machine). I can get some good hits with mine, but Galactus was getting fantastic hits too, and if you check out some of the Touro vids, their opponents are getting serious airtime!
The top-end rpm might be a bit high but it's easy enough to drop that down if necessary. Either way, it's gonna hit hard.
