Early on I tried a 4# striker spring. It makes a significant difference in pull weight. Probably the biggest of all changes, IMO. But why? I couldn't really answer that, went back to stock 5# spring and never looked back.
I DID end up with the NY1 spring and 3.5 GLOCK connector and like this combo. Tried Ghost but I like the Glock and Sherer connectors better.
