The nova is the trilam or “membrane” suit which is what you should get and what I got. For cool water I just use an inexpensive moisture wicking base layer with a thinner wool top and bottom. Got em off Amazon. For “colder” water I’ll add a “polypro” top and bottom, or waffle top and bottom as some call it. All can be purchased relatively cheap. For really cold water I have a fleece onesie that I bought used for like $50. Your cold tolerance may be different than mine. I get cold easily.
I got the QCS over wrist seal system, it’s oval and more aero dynamic and looks cool to me

plus you can change your own silicone seals very easily. The oval system is not compatible with dry gloves to I had to buy the ultima drylove system when I dive dry gloves which isn’t often.
JUST MY OPINION.
please let us know if you have any more questions.
