Thanks for sharing all that, appreciated. I had looked at that particular store last month and they were sold out of the lighter springs, but I'll check with them again to see if that's changing. And great point around switches being stuck with the lighter springs, definitely something I'll have to watch out for if I ever get that far.

I've also enjoyed Topre switches in the past, I remember those feeling pretty light as well, although I can't quite recall how my injured joints worked with them, that was in the healthy days.
