I agree that short arms like the 15 are very limiting, but I'm not sure this type of frame would support a heavier, larger head. That would be a good question for the manufacturer. I've wondered if my 31-20 with a 10 1/2" throat space would or could be put on a frame (if I could put a motor on the back of it). I would worry about the weight though. I know that even that throat space is limiting, but with no hope of a long arm in my immediate future, it may be something to ponder.
