Recently donated my Spitty F4 97s to a homey, as I feel like this new F4 93 formula does all of the things the 97s do, but better.
Ride is even softer feeling w/o being "bouncy," the slide actually sounds better AND they break into that slide w/ less effort than the 97s require.
I am noticing some light "gouging" (for lack of a better term) in the riding surface after running the usual speed checks on these SF hills. Jury is still out on durability & wear factor for these fun little fucks, at least until I get more time on them.
Over all, I'm liking them a lot as a softer option, even though I'm pretty sure these will be a one time thing for me, as the F4 99s still feel like home.
