Just a followup to this and a DM conversation with
@sharko108:
As I have stated, the Ultima rings are a good system but the company redesigned the glove-side rings to add the "twist" tabs to facilitate separation/removal of the gloves post dive.
While that is a positive change, it in itself makes a statement about the Ultima rings themselves. If there was no problem with the Ultima DGS, Waterproof would not have made the modification, and then softly introduced the "Twist" system to the market, while waiting to burn through remaining stock of the original version, before beginning widespread advertisment of the "Twist" version of the ring system.
Its good, but it addresses complaints and the issue that the rings can be hard to separate after a dive...so much so that they resorted to the "Twist" change.
I don't think you will regret purchasing the Ultima system...but if you ever have the chance to try the Rolock 90, you will most likely think "why didn't I
invest in these from the start".
There is an old english expression when it comes to purchasing tools and other things that are of quality and expense:
Achetez une fois, Pleurez une fois.
