In my Gen4 guns (with Gen4 trigger bar) this gives a pretty decent rolling break with a fairly forceful reset. It varies a bit more in my Gen3s, with a FDE 19 that gives a much crisper break, while another 19 and a 34 have the rolling break. I have had no reliability issues in thousands of rounds, including several training classes. I carry my G4 19 with set up daily in plain clothes, and have full confidence in the trigger set up. I do change the NY spring with the recoil spring as part of PM as I am not aware of data on how long the plastic will work reliably without the coil spring. It is a cheap part, and I do not mind the extra couple bucks.
I did try the EVO for a short time with the same NY1 set up. It gave a much mushier feel, and I also had some of the weird hitch others described when hand cycling in dry fire. After trying it in several pistols, I relegated it to the parts box for now and will stick with my factory connectors. I may try it in my 17L, as I shoot that relatively infrequently and only recreationally (for now at least).
