i jam the 9's work well for me unless im drop tuning the crap outa the guitar then i'd put a heavier guage
10-46 but im a heavier player
Twin variant excelent
It is a good choice, depends on the style of very touch....
I'm switching to .010's for a less bright sound but i do like the feel of .009 better. You can pretty much use anything on a Floyd with proper setup.
