Don't know if it's the same presentation but I saw a similar one previously. At the time I decided to give a MRS a try. Took a while to find one, eventually settling on a rEvo one on my JJ. Once I started using it I liked it especially on long hangs as it just took the weight off my jaw. Not a total convert though. It can be a bit a faff with a hood. I found getting the mask strap and MRS strap comfortable a bit of a hassle. So I started to go with the mask strap under the hood approach. Would agree with the comments above. For general dives I would use one, however if it's a training dive that involves lots of bailout or mask skills I wouldn't.
