what kind or rubber are you guys running?

i'm currently running clincher clement PDX 33s.  they are fine for the most part.  they roll well and are awesome in wet grass.   my only gripe on them is the transition from center to side is a little bit loose feeling when you're riding at speed on loose over hardpack. 

the CCCX series i'm participating in is pretty much always dry and loose which is why i'm considereing something else.  the surf city series typically has grass and it's usually wet when i'm racing so the PDXs will be fine for those.

i'm liking the looks of the captain CX 34s.  i've had good luck with those on my SS rigid mtb.
