When I realized I was going to have to give up on the Vikings, I talked to Mike. He very sweetly sent me both sets -- the Glove Lock and the ones I bought -- so I could decide which one worked. The Glove Lock seems to require a splined part on the suit side, which I don't have. It will not go directly onto the suit rings I do have. It is also absolutely enormous. The ones I bought appeared to fit and work, and did not increase the overall profile of the rings. I did not pick up on the o-ring problem when I was deciding which one to buy.
I am hoping either to get in on Peter's purchase, or get the information on which o-rings to buy. Yesterday, despite silicone spray and SEVERAL attempts at getting the gloves on perfectly, without pinching the o-rings, I ended up with two wet and very cold and painful hands. Right now, I'd say this glove system is one of the worst performing scuba purchases I have made in the last six years, and I would not recommend them to anyone.
I am supposed to get my other suit back (I thought it was going to be here already) and Peter has probably given me the solution. I'll just put the tech skin on the other suit and go back to the Viking rings, and this suit will become my warm water and travel suit (and travel only to places where dry gloves aren't necessary!)
