WNTITAL: I ended up going with a 335mm Hagon shock, I think. May have to double check the length. But I removed the springs and fully compressed the shock to see where its bottom out point was. You're right, my measuring point was from the rear brace to the top of the tire. I ended up having around 1.25-1.5" clearance. I've ridden it pretty hard without bottoming out and I've had a few guys w a couple more lb's on them ride it with no issues. But to be on the safe side, I'd definitely remove the springs and check the distance.
