Soft handles/socks:
Ihave a number of ones I use/like
OxyCheq Universal, OxyCheq (specific version), some other models, ....
I have a couple universal hard handles made here by a guy as a project a few years ago, but never implemented them as I like the soft handles
That Oxy Universal one looks VERY similar to the soft handle I got from DGX. I like it okay, but I don't like the way there ends up being what seems like extra material around the thumb area when it's in use. Plus, the way the Velcro works, I have to put it on my bare hand pretty tight for the Velcro to fold back far enough for the tail of it to fasten down. I'm not sure if I can actually wear it with 3mm wet gloves.
That Oxy Raider sock looks pretty cool, though.
