My issue is weight I likely wont carry the tube. When you're cutting tags, and ditching gear most sane people would take you know you're goofy about it! LOL I have a good spot in my pack where it can fit, but a fall can be brutal on stuff, the tips are slightly exposed though they're usually in a sock unless its sheep than the sock stays home. Inside the pack its usually ok.....strapping to the outside was a baaaad move! A brand spanking new bow look liked it was hit with a geese grater and run over by 18 wheeler!
There was a fella up here who had a site, Alaska string works, who was doing conversions like Jim's doing (sweet vid btw Jim!). I had hoped to find him but so far haven't had much luck getting a return, and it looks like his site is down. It's a small town and even smaller trad bowhunting community so I'll likely run in to him eventually if he's still around. I'm holding off for a bit. A 1 piece Berry or 3 is on the radar LOL!
I just wanted to mention this as strapping a take down has issues folks don't really think about. Doing it once or twice you might be fine, doing it on a regular basis creates a hole separate ball of wax. Nothing wrong or not knocking a system or company, just looking for the best option there is for it.
My buddy uses the metal sleeve system, though I really like the bows (Wes Wallace), I cringe at the thought a fall could have on that sleeve. Throw out 2-3000 bucks on a bush flight and squash it, you're likely done! A guy hunting off the road system can get out, still stinks but with a backup at the truck/camp or at least civilization reachable, you have options.
