@Thayer I think the problem with the longitudinally split pole is even with gorilla tape the force to slide apart rather than bend is likely to be strong enough to cause slippage, further split propagation, and possible eventual complete failure, plus higher bend radius at the fix. In our case too much tape would also cause us a problem as the bit of pole has to fit through a sleeve of material.

However I reckon it would surely hold for a while at least. We've used this split one at least a couple of times without any mending, it just kinda changes the shape of the tent a bit. (And gradually gets worse.)

Also going to depend on the pole thickness and the radius it needs to bend through, what amount of force is involved. For our poles on a fairly big tent the force is relatively high.
