Sorry for the delay in answering this. Been real busy. But I use the oceanic. It does fold up easily but when deployed i find it no different than a non folding as far as performance and reliability. Does not kink, easy to breathe thru. As far as easy off and on replace the factory clip. It sucks until it's really broke in. I get replacement quick release clips from the shop. These you just push a little tab and it comes off and on easily. One piece stays on the snorkel body the other on the mask strap. I originally got mine from a cheap bodyglove set i got at Sam's club to use just for snorkeling before I started diving. I still use this clip and have gotten a couple more for my other snorkel and my son's as well. They are well made have, never broken one, and are cheap.
