I own a JJ as well and I have dived/own units with drysuit stye dump valves and much prefer the basic pull style. I actually find the adjustable OPV to be more "task" loading because to start you have to crank the thing closed, crank it open when I want to dump gas then crank it closed again. And repeat this over and over.

Can you not tap to dump like on a drysuit? That is the way the Prism version dumps. I'm a mouth/nose venter so I don't ever really use my opv except in a bailout situation.
