I have DSS bp's, I think they're great. A lot of attention paid to detail. Really top of the line... but from what I read the issue with DSS wings was that in order to work on the bladder they had to be sent in for any kind of work whereas your other wings (I too settled on VDH 35# single wing) are put together with a zipper?
Maybe not the end of the world and really how often do you need to service the bladder.... but still, for someone that was so innovative and cutting edge makes you wonder why DSS were sewed up?
Oh,..... I only had a a little interaction with Tobin... I was told his demeanor was a bit crude...and boy he did not disappoint! Kind of reminded me of Ian? Yeah? (for the record, I gained a lot of knowledge from both of them... even if they aren't the worlds nicest people, lol). Dealing with either one of them is / was kind of like going to one of those offensive restaurants. You know you're getting good stuff, but come prepared with extra thick skin!!
