SO that would be the the A-Clamp inducing failiure of the body on some Mk20 1st stages due to the A-Clamp retainer being over torqued and the design being flawed? Certainly something worth checking if you have an old A-Clamp Mk20 and it has been serviced without regard of advice from ScubaPro and the free replacement A-Clamp retainer. Heres a good photo of what happened to some Mk20s that had the old A-Clamp retainer

Or are you refering to Titatnium Mk20UL being used for O2.. (only in america lol)

Surely you cannot buy a Mk20 new with the latest 2nd stages attached? Surely it would be the updated MK25 which never had the probematic A-Clamp retainers.
Or is there another issue that we should be aware of?
GUE use DIN regs so this would ALL be irrelevant, as I dont dive DIR perhaps someone else would care to comment - so much crap on tinternet - but some good photos
What RichW said makes a lot of sense, you dont want to be part of the ScubaPro testing team - stick with the older reg bodies that are tried and tested.
