My $.02 vote is for full hollows
Hi Ed,
At this point I vote for full hollows, because I started with two antique-store razors, a full-hollow and a wedge. The full hollow was the only one I could get sharp enough to use. I've got a thick beard and thought I'd need the wedge to get through it, but the hollows work fine. I haven't tried the half or quarter hollows; eventually RAD will hit again and I'll look for some.
The only downside I can report on the full wedge is that it is really a lot of work to hone. That's why I haven't used it yet. If you've got one you're eager to use, but it's dull, send it out to a pro for honing.
