In Feb 2021 I replaced the Lightspeed in my RV10 with a PMAG and it now has 200 hours on it. A year later, in 2022, I replaced the Slick mag with a second PMAG. I have been very satisfied with the operation and performance of two PMAGs on my RV10. Hot starts were an issue before, now not at all. I have had PMAGs on my RV7a since I built it 17 years ago and 2200 hours, so I certainly have a preference/bias to PMAGs.
