I wouldn't be the least bit concerned about the limb bolt TD systems wearing out. I love the Bear Latch system and have two of them but I think they'd wear before the limb bolts and I think both styles will outlast a couple generations of us. The limb laminations themselves might fail before the attachment systems.
Like others have said, I very rarely take my TDs apart anyway -- only if going on a long trip where fancy packing is required. I treat my TD bows like 1-piece bows. The great thing about TDs are many: you can change limbs (weight, length, and appearance, portability when needed, and they are a bit heavier than a 1-piece which I generally like.
By the way, if you can swing a Pittsley Predator you are in TERRIFIC shape -- look no further! I believe the smoothest drawing bows I own are my Predators. My son owns only one recurve and it is a Predator -- he sees no need for another bow -- too bad for my budget I don't share that strategy!
