Best Drysuit Undergarment?

[Spamcan]

OK, I know this is very subjective - it varies greatly per person. But, hoping to get some feedback...

I currently dive a DUI TLS350 with some fleece items which works well in San Diego waters (low 50's to mid 60's, above that I dive wet). But now I'm heading up to the Seattle area which I hear can get down to mid 40's. So I want to get a good jumpsuit - I'll figure out the thickness/heat rating after figuring out my questions below. Been looking at DUI, Bare and Whites.

So first...the materials - fleece versus Thinsulate. From what I've read Thinsulate is the more comfortable. But I've also heard they're not easy to wash - special instructions? What's your pros and cons overall?

Second...manufacturers. Of the 3 mentioned above, what's your take?

Thanks, Spamcan

I have the quilted fleece from Ron on E-bay. Great prices and pretty warm too. He has lots of different weights of undergarments. I do most of my diving at a lake north of Atlanta. I've heard from some here locally about surface temps in the high 30's to mid 40s still!!!. Georgia, as far as a usual winter is concerned, has been unusually cold this year. Snow in Jan, Feb. and March! The last few years maybe no snow, at all.
I'm going to give it a few more weeks in the 60s air temp wise to warm things up before I get in.
I have dove his quilted fleece suit down into the 50s and still pretty warm in my Pinnacle EVO2.

I have a DUI 400 gram Thinsulate jumpsuit. It is very warm, but is very buoyant, and is bulky. I prefer fleece.
