I kinda like trying to remember this stuff...
My early bag was all over the place, but when I finally figured out slots it was in '95 and it went:
Putter: Aviar
Mid: Roc
Driver: Cyclone
Turnover Driver: Stingray (yes, I'm so old I played when the Stingray was a driver
)
Overstable Driver: X-Clone
My bag has a lot more slots now and a lot more molds than I carried back then, but Rocs and Cyclones are still in the bag. Rocs I pretty much use the same as I did then. The slot the Cyclones are in has moved from primary go-to driver to stable control driver, so I don't rely on them nearly as much as I did 20 years ago.
The Banshee took over the overstable driver slot from the X-Clone when it came out ('97? '98?) and has been in the bag for a long, long time as well. I've thrown Sentinels for a long time as well but I have no idea when I actually put them in the bag and left them there. Comets I've thrown since '95 but they are a constant in-out-in-out love/hate thing.
Avairs come back every now and again. I love Aviars. I love Wizards more, but I love Aviars too much to never have them in the bag. They just are not a constant thing like Rocs, Sentinels, Cyclones and Banshees are.
Really, other than my constant putter tinkering the slower end of my bag is pretty constant. Once you get past the control drivers into the distance drivers, the discs change almost as often as my underwear. The slow stuff is pretty set, though.
