ENO trials, be sure you take the trials version not the other ones which will break ENO trials has lasted 1 year and 2 months for me, without skipping, just need to clean it after every 3 months which is very easy to do i dont have any personal experience with tensiles but they seem to be good also monty freewheels and tryalls- mine lasted only 7 months though and ACS after 2 months it was smooth from the inside, pawls didnt have a spot to engage anymore
