I used these pretty extensively when I was on 100. They are very nice as far as shaft couplings go.
I've used these a few times as well. Some things I've learned about them from my experience: Use a larger outside diameter if possible. It will be able to take more severe loading and misalignment. Use Hytrel spiders/inserts as opposed to the Buna-N rubber. The rubber ones cannot take as much torque and can wear out. Rigidly mount whatever is on each side of the lfex coupling. Flexing of the mount can cause flex coupling failure.
