I would consider myself a 98 year old man trapped in a 38 year old body, so call me excessive flow. If anything the LM is more restrictive (to me) then the Trigon (at least at 1st, subsequent relief is easier).I had nothing but troubles with the Tigon. Even to the point I got a replacement for my defective one. The new one doesn't leak as bad. Keep getting BS answers of "it will have issues if you have excessive flow" and that is somehow user error. It is a larger than normal mounting holes so it you get one, you are stuck with it.
Now the Light Monkey Tinkle has always worked correctly. Would do that one again without hesitation.
Does it always leak, just sometimes, after a full week of diving?
Mine leaked once.. it was because I wasn't cleaning it enough. Tore it apart and all was good after that.
