Springfield RO trigger

Looking for opinions. I have a RO that I put an AA 22 conversion on. 7# recoil spring, 19# main spring. I don't like the trigger pull. I'm thinking of getting a KC roll trigger set. I haven't shot the 45 yet as I'm trying to get 22 working at my average score, I'm down 10-15%. Those that convert back and forth, do you change trigger pull or stay at 4 pounds for both? What do you think?

If your practicing for EIC, 4#, for .45, 3.5#
For .22, 2-2 1/2#

I use a dedicated lower for .22
I use the conversion on my EIC .45 for practice

I stay just under four pounds for both .22 and .45.
