I would add, although this is a matter of preference, that you should go more towards a half hollow or wedge if your beard is very thick. They're more rigid, so I find that they do better with thick beards than a full-hollow.

The winter of 09-10' I grew my beard out VERY big. I kept my neck trimmed up for comfort, but otherwise I completely stopped shaving for about 4 months and looked like grizzly adams.

I hacked it all off when the warmer weather came around with a Frederick Reynolds wedge, and while I had to use short strokes, I didn't actually need to stop to re-lather at all, nor did I have to rinse the blade until there was so much beard and soap on it that I couldn't see what I was doing.
