I use a compact but run the 34 as it allows me to use a 12-23. It
results in even less chain and the 12-23 shifts better than the 12-27
as it does not have to climb to the limit of a standard road
derailluer. As for the big ring, I seldom use it, as our courses have
very few fast paved flat sections where you need a big ring. I think I
would go with the smaller big ring like the 44, as it is more likely
that you will be able to use it and you can make the chain even
shorter. You can go very fast in a 44/12 or 13.

Dan,
If you go compact, do something like 44/36. And run a road deraileur
on the
rear. You want a chainring you will spend most of your time using. The
other
one is for 'special' situations -- like climbing hills or sprinting on
the
flats. If you feel confident pusing a 44 most of the race and shift
down for
the hills, go compact. If you would rather push a 39 for most of the
race
and shift up (to say a 46) for the fast bits, then go standard.
Cyclocross benefits a tighter chain. Use the chainring, cassette,
deraileur
combination that will keep your chain tight and still work for you.
Dropped
chains suck and the WILL happen. A flappy chain is just asking to
drop.
FWIW, I run 46/39 with 12-27 on one bike and 48/38 with 12-27 on
another. I
think I like the 46/39 better.
And someone around here might mention that Dale Knapp runs a 44/39.
Methinks
he mashes the 44 most of the race ...
