Thanks for the replies and thoughts. Not sure what I'm going to do. I'm rethinking the need for hardshell per some of the thoughts posted on here. I have a Sunlite bag that's quite water proof (flap like ortlieb + roll top)and surprisingly nice, but don't have the 31.8mm mount, and Sunlite has been telling me they'd send me it for about 4 months. Thinking about splurging for an Ortlieb, but seems like a lot of money especially considering I have a similar sized and waterproofed bag.
