Hadleys are my favorite hubs. Durability problems are with the 108pt model, as only one pawl engages at a time. I only run the 36pt models, all of which have been bulletproof (three pawls engaging simultaneously). Had a King hub before, and the Hadley 36pt engagement is "plenty fast" for low-speed technical riding, whereas the standard 18pt Shimano/Hugi engagement is not fast enough.
