I too wasn't a big fan of the Dyneema as anything other than a liner- at first, but after purchasing the PCSB at the last minute before a trip, and having it work so wonderfully...and then purchasing a couple of Shop Bags....well, it's really grown on me as well. I still don't know that I'd purchase a Synapse or Co-pilot with a Dyneema exterior, but then again, who knows?!
The black/UV is a great combo. A black/UV Synapse was my first TB family member. It blew me away! I still really like it, however, Navy/Iberian is my MUST-HAVE combo. In fact, when the Synapse was later offered in Navy/Iberian, I snapped it up...even though I already had one in black/UV :) Sad, eh?! I still use 'em both though :) To my hubby's dismay, I like to mix up my bags...frequently! Different colors, different styles :) At least it makes holidays easy for him ("Hey honey, what bag do you want for your birthday?")....the funniest part (to me!) is that he STILL likes to shake his head and say "I just don't get why you want ANOTHER bag"....tee hee!
