I have a Kathy Kelly case strung longbow case that fits my 66" ACS nicely.
Predator Man, I'm assuming this is for the 66" ACS you mentioned in another thread? Ive been looking for a hard case for sometime as well, but no luck this far. I tried using PVC but couldn't find any big enough. I also found a 6" carpet tube, and its inside diameter wasn't big enough for my unstrung ACS due to it extreme reflex/deflex design. I would have to flex the limbs just past my comfort level in the tube. If you find something that works, please let me know, as I'm still on the hunt.
