I just bought a Think Tank Streetwalker Pro to replace my beloved but small Fipside 300. The SWP is great and it holds all my gear nice & snug now but it's a tad too bulky to carry around in crowed bars and clubs when I shoot bands.
Been thinking about getting a second smaller, more discrete bag to hold my gripped 7D + 3 lenses max (Sigma 50mm, EF-S 17-55, & 70-200mm f/2.8L II) and maybe a 580EX II. I really like the messenger-style bags and think I want to go with one of those. Any suggestions on what I should look at or stay away from?
