CZ Custom is just as good as CGW, other than possibly the reply time of customer service. I've heard great things about CGW, including their quick personal communication. I've ordered guns from CZ Custom, including a number of worked models- they are top notch. As CZ fans, we are very fortunate to have two great services to chose from. I would definitely order again from CZ Custom, and I would love to try CGW in the future.
I would suggest that you get a factory model of your choosing, and run it for a while. Then, determine if you want to modify it or not.
I have a 75 Compact and a Shadowline Compact- both rack about the same.
