Yep, that's it, that's where I was going next Toomuchsawdust after I saw the Imp video. Been busy on a project last two months, no time! You might have trouble getting that to release with the deepish groove, will be interesting to see what happens! It will just be a matter of tuning it to find the sweet spot.
Edit: I looked at you photos again, looks just about perfect on second look, should release fine ;-)
