Do you have the older one? I don't understand " The relief worried me a bit"

I have the new one installed on my Santi. I'm at work at the moment but will post my impressions later today.

Ah I get it, you mean the height of the ring.

I had the new Sitech fitted to my Santi by DRIS. Initially they advised that they'd need to remove the warm collar which I wasn't so keen on so they went back to the drawing board. They made contact a day or so later advising they had worked out a way to keep the collar which I was very happy about.
I didn't actually want the neck system as I'd heard from Santi and several SB members that it's not good for small framed people. I previously had an issue with the suit leaking through the inflator gasket and sent it off for repair, not DRIS, it came back and within one day started peeling off. I was a little concerned that if something as simple (?) as replacing an inflator gasket was done incorrectly (?) how was a full neck seal replacement likely to go. So decided I'd get the neck system so I could replace neck seals myself.
On land I notice the ring is there, it causes my harness to try and slip off my shoulders. I can feel it slightly through my BZ400. Underwater I don't notice it's there at all. I have noticed a reduction in mobility but am unsure if it's the ring or the thickness of my new BZ400, I suspect the latter. I only single tank dive so have no idea how it might affect the mobility required for valve drills.
I notice that the top outer edge of the inflator gasket is in contact with the ring and looks like it's putting some stress on the gasket, it looks like it's trying to unpeel but the boys at DRIS have both glued and stitched the gasket so maybe it will hold up just fine. Time will tell. It no longer leaks so they did solve that issue.
Prior to the neck ring my suit folded very nicely and easily, with the neck ring not so much.
I havent tried to replace a neck seal yet so have no idea how easy or difficult that may be. Looking closely at it it doesn't look as accessible as one of my buddy's older versions. The securing ring looks well buried.
For me the ability, hope so anyway, to change my own neck seals makes it worth it. However if I had the knowledge and/or experience to confidently replace my own latex seals with glue etc I'd probably not have bothered. I don't travel dive with my drysuit so being able to change seals on a boat or it ruin a vacation is not a concern to me.
I've only done 10 or so dives with the new system so cannot comment on the longevity of the silicone seal. My layex seal occasionally leaked, possibly because I trimmed it prematurely, possibly because I'm skinny, not sure. The silicone seal has not once yet leaked. Comfort wise I don't notice any difference. I am able to turn my head without it leaking, the latex seal would leak but maybe due to my trimming?
I don't love it, I don't hate it. I can't compare it to the older system as I've never tried it so couldn't say if it's an improvement or not. If you need to be able to replace your own seals in a hurry without the use of chemicals etc it's a no brainer.
My opinion of neck system aside, DRIS did a great job fitting the neck system. They also managed, although looks a smidgen rough (I'm a bit OCD) to replace and actually seal my inflator gasket.
Since I've had the suit back from DRIS I've not had one leak. Based on my experience with not only the work done but also the communication throughout the process I have complete faith in their ability to work on drysuits and at the end of this season will be returning my suit so they can fit the Kubi Fitted a glove system to my suit. If it means anything I'm happy to pay the shipping from Japan to DRIS because I believe they will do a good job. I trust them. Maybe they can make my inflator gasket look prettier at the same time
Hope this was of some help.
