I’ve never seen a takedown come apart when assembled correctly. The one problem I have with takedowns is their weight the fact that you have to assemble before you can use it. The shot opportunity may come when your not ready and probably won’t hang around for you to assemble the bow. I might add the less parts you have to carry the better, If overall length is a problem I would suggest a shorter recurve, they don’t pull as smooth but are just as effective.
On a long hike and backpacking, you have to go in to resupply, and conceal-ability is the issue, during stops at campgrounds and at stores.
