I have the DC gloves for my DC suit, but not tried the neoprene gloves. I talked to a few local divers about the neoprene, which they had tried at one time. Every one of them said to buy the standard DC gloves. Sorry, but I don't recall why.
I also use their ring system. It works well, and mine is mounted retaining the wrist seal of the suit.
It's the ring system you want. Easy to add to your drysuit.
I have installed 4 sets of rings in DC suits, and I'm here to tell you that it is far from easy (if you are retaining the wrist seals). The shop I bought the suit from had a horrible time installing other customer's rings, and "preferred that you do it yourself". I ended up talking directly to DC for help, and they freely admit that it's "quite challenging".
Having said that, once you have them in place, they are wonderful. No leaks and easy to don/doff the gloves by yourself. The gloves are lined with fluffy fur-like material, and when combined with the glove liners, will keep your fingers toasty warm.
I would recommend, as was told to me by DC, to purchase 2 extra o-ring gaskets. If you end up buying the DC rings, PM me and I will talk you through placing these extra gaskets.
