Everyone seems to like Hetman's, but I've always had good luck with Alisyn. For those of you who have used both, what's the difference?
The Alisyn has performed vastly better on my 621 than the Al Cass I used to use. I didn't have problems changing over, though, and did so with just a careful wiping of the valves and casings. No gumminess that I detected.
