Mr. Shooter,
I doubt that NHC makes a bad model. Once you are in this ballpark, ya gotta go where your lust takes you. If there's a particular feature you don't like or want to change, there's a good chance NHC will do it for you.
Since I have a Predator II, obviously I have learned an attachment to the gun. But let's just say that the Costa and PredatorII are equals.
I spent the night at one of my ranges in the company of the owner of the facility. He has seen 1000's of guns pass through and says without equivocation that my NHC is the finest 1911 he has seen and shot in his entire experience.
To night, I got some coaching from the owner and operator of a local shooting academy. He has taught 100's of qualified shooters including many LEO's and other professionals. He asked if he could try my NHC. His reaction (I'm quoting him) "This is the softest nicest shooting .45 ACP ever..." followed by a confessiion that his nipples had gotten hard. I kid you not and there were other words of amazement. Later in the evening he asked if he could try the gun again.
My advice? Indulge your fantasies! You are only a youngster for a short time and the world keeps pushing us to grow up
