Perception is one of the best. I have run it since its release in late 2013 and have to comment on the cracking that I have not witnessed but I clean and treat my fly line on a regular basis which should be done like anything else, it only takes 5-10 mins! If you wash your car regularly why not your fly line. Only thing about the new rio lines I have a hard time believing is the "self lubricating " which rio boosts about perception.
