I got a bunch of free Gravis filters. The sole is a little stiff for my liking, but the hold up pretty damn well.
Here are some other companies:
STAMINA, look at that team
DUKES, Wray was on, so I liked it.
A-TEAM: Mosley, Johnson, Thomas, Mayhew...
I hated their graphics back then... they were horrible.
DROORS.
I absolutely loved that stuff back in the day...
