This is interesting, and I hadn't thought about it until this above conversation. I find myself in this game at about the same point I am in my irl game.
Irl, 11 years ago or so I started with an innova starter pack except for the wizard that I already had. I added a destroyer, teebird, firebird and that's pretty much my bag. I never was interested in trying the newest greatest molds - my brain just isn't made to store all of that information about different brands/speeds/plastics - especially when they're changing every day. I stick with what I know, my bag today is very much the same as my bag 10 years ago.
DGV - I never thought about it the same way by any means, until this conversation, I realize my approach is exactly the same. I built up my current bag by level 30 or so. And they work fine, I have no real desire to try out all the new discs and attributes.. I can only process so much. My bag today is the same as it was 60 levels ago. 6 discs, no putter, 2 ballistas, w/acc explorer w/acc musket.
In both instances I imagine that I could be a better player if I just tried it... *Shrugs*
