I'm happy that you are enjoying your 97B"E" as much as I am mine. Although I have certainly had some success and much enjoyment out of the polymer P-09, P-07, and P-10C pistols, I'm still a steel 75/97 steel gun guy, I'm afraid. I have to do so much to the grip and trigger to get my hands to fit the polymer frames correctly that the guns look seriously defaced after I get them the way I want them. They are downright ugly when I'm done. The 75 and 97 don't need near as much work and are almost presentable when I'm done.
Accuracy wise, CGW has found the secret, specifically for the CZ's. Produce a tight barrel bushing that is still serviceable and 100% functional--10x for the 75 and "E" for the 97. Eliminate the one area of slop (the factory bushing) in the barrel to slide fit that all steel 75/97 series pistols seem to have.
What is amazing to me is that both of my P-09's without barrel bushings, but manufactured with modern tools, have excellent barrel to slide fit at a good price. My P-09, P-07, 75B, and 97B are ALL excellent shooters, historically producing almost identical group sizes at 50-100-200 yards when using a small 3 moa red dot sight from a wrist rest. I'll never buy a a custom 1911 for bullseye matches. No reason to do so, as I have a "custom" CGW 97B"E" instead! Not that there is anything wrong with 1911's, I have one. I just no longer NEED one. All I need is ammo and my health.
