You'll probably get a different builder for every reply that you get. At the end of the day as long as it runs and you get a load tuned for it, you'll be happy.
To answer your question .... I have your #1 choice in 9mm (purchased used from USPSA classifieds) and I'm having your #2 choice built (again in 9mm) which I should have in about 4 weeks if STI finished the cutom serial number frame. Matt will build the gun anyway you want ... you can use the hybricomp barrel with no holes, or start with just one. He can always add another hole or two if you decide to later down the road.
Enjoy the trip, shooting Open is a lot of fun.
