Underwear for UK

[Robert Cook]

Guys, I am currently living in Australia, but will be doing a couple of years in the UK & Ireland, beginning in October. I currently have a membrane drysuit (Otter Brittanic), and I'm wondering what underwear I'm likely to need for over there. I'll also be doing a CCR trimix course after I arrive, so I'll be looking at some extended runtimes as well. At the moment I've got:

Xerotherm Arctic - great suit. It's enough on it's own over here, and I'm assuming that I'll want it as a base layer over there.

Weezle Compact - Not sure if this will be adequate - I did a 40-ish minute deco in this plus the Xerotherm in a flooded drysuit at 12 degrees last year, and ended up cold bet not dangerously so.

Otter Arctic 300 - I got this for a trip to Antarctica earlier this year - will it be overkill for the UK?

As I'm trying to keep the amount of stuff I'm carrying at a non-stupid level, what I'd ideally like is a single undersuit to be used year-round, with the Xerotherm added in winter. Is this realistic, and if so, what would you reccommend?

Thanks,
Robert

Hi Robert,
Me and Mrs were using 200g undersuits from october and added cheap thermals when it got a bit colder, with the added thermals we were toastie down to 4degrees 40min dives.
