eb evo kc9

Being 67 years old but just getting into 1911's I've been sticking to the "Beginner's corner" but wanted to ask opinions about an EB I ordered. My very 1st 1911 I only got about 5-6 weeks ago, A Kimber Aegis Elite Ultra II in 9mm. It's at my 1911 gunsmith getting 5 EB parts installed on it...
