ok, is your disc bending when you take it out of the bag? this is definitely an important part to note for future bag runs
Yes, I have to bend it to take it out. Fortunately my left-most disc tends to be a Vibram, so it bend a bit, but mids don't bend all that well (especially if it's an MVP mid). In that case I have to use some bending (usually of the flight plate) along with twisting the disc up and over the top of the others and bending/stretching the bag a fair amount.
I get that discs can't slide in and out super easily, or else they'd fall out all the time, but the rounded edges kind of suck… as I thought they might. I prefer the square edges as on the Contender. The Catalyst could have used "less rounded" edges even if a true corner would have been awkward given the "standard" orientation of the zipper (the Contender of course zips the other way).
