I have 240 gsm paper but that's to toothy and it really soaks in very quick. The best paper so far is Daler & Rowney 220 gsm heavy weight cartridge paper. It's very smooth. I also have 220 gsm of Schoellershammer watercolor paper, which has a texture I don't really like.
I can remember you use Neenah? I can't get that here =(
