Mike, Sounds like most of us 23' guys are in the same boat so to speak.
The Bird has an o.k. size hold, but almost too small a hatch lid to stuff the right size bag down in there. I would be up for a bag that would fit in there perfect. Would the bag flex a little more if the foam was cut and sewn into a few strips on the sides instead of one big sheet to finagle into the hold? I'm in if were making a run on them. Let me know if you need any help Mike.
Thanks, J
