250gsm marino wool has become my favorite. It feels great, smells great, doesn't feel wet. In a compressed neo suit it's great for me down to about 66-68F before I add another layer. I'd actually like to find more marino that's maybe a little thicker to layer up.
For colder stuff I have a fourth element arctic.... buy once cry once (I cried a little longer than most, but it was only once!)
