Thanks guys. It sounds like it's mostly a preference thing so I guess I'll have to pick one up and see if its for me.
this is a slightly tangential observation, but the use of the term "closed comb" cracks me up. Once you close it up, it's not a comb anymore, right? It becomes a safety bar.
I guess it's kind of awkward to say "open comb versus safety bar," though.
Oh, well. Carry on.
