OS 7 speeds are in my personal pantheon of slots that are fun to mess with yet never are essential to my game. I've tried my darndest to keep an F1 and an EXP-X in my bag at various points, my thought being that they cut through the air a little better than a Gator and are more shapeable than a Firebird, which is true, but I just never end up needing that shot, and when the situation comes up where I may, it's not like it's the ONLY disc that would work. And it doesn't seem to work the other way, I wouldn't feel comfortable shelving Firebirds and Gators and using an OS 7 speed for both slots, maybe if I developed my game around a disc like that early on I could have, but at this point I would feel like I'm trying to solve a problem that doesn't exist. So for now it goes in the bag along with the other discs that are spectacular that I just can't fit in. Rhyno, MD4, Drift, EXP-X, Thunderbird, Ballista Pro, you are gone but never forgotten.
