Hi Adam,
I am also quite used to dive in cold waters. These Lakes in the Alps are fresh. In 4°C water then, atleast for me, I need them dry gloves. I also have the INON's. So, I have
There are a lot of different dry glove systems and all of them have their pros and cons. If you are happy with your system don't change them.
I am personally using the Rollock system, mainly in order to be able to put them on/off myself. The gloves came without Liners. As strange as it sounds it is actually an advantage, since I can vary the thickness of the inner glove. I am using a thick Thinsulate as Liner on my left hand and a thin fleece glove as a liner on my right hand. That gives me a warm and cosy left hand and a possibilty to twiddle around with those knobs of the INON's. This way gives me a lot warmer fingers than neo gloves. I also find that I have better control of the different knobs than with neo gloves. If I have the thick Thinsulate on my right hand as well, then I am also not able to fiddle with the Inon knobs.
I don't know your system, but normally you can change the rubber glove itself. Most of the drygloves are simply Chemical protection gloves and can be bought in your nearby handyman store. One of my mates got himself orange gloves that way, so that his students would easily notice him.
I did a small modification for basically the same reason on my Zoom knob on the Housing. I drilled a hole and screwed in a small metal rod in order to get an easier grip. I don't think that I would dare to do the same thing to the Inon's.
I am not sure that my comments will help you, but I wish you good luck.
