I don't like more than 2 discs in each vertical slot because they're a pain to remove then, and the inside storage sucks to get at.
But, 3 drivers in a side pocket works very well. I was worried about overstretching, but so far it seems to be a non-issue.
Lately I've carried:
Vertical: 2 putting putters top, zone and proxy middle, DX roc and eagle bottom.
Left side: roc and stingray bottom, PD/firebird/wraith top
Right side: Teebird/Leo3 bottom, 3 valks top
It's worked quite well.
Edit: Try moving mid pairs to outside pockets and vertical storage will likely seem slimmer.
Just played 27 at my local short course. Definitely needs some rearranging even though I only really used 4 discs the whole time. I'll try mids outside for sure.
