> And when you’re trying to sort through 3-5k+ photos shot over a very busy weekend, comfort is the deciding factor.
From one phtographer to another, and not to be a dick, but if you're shooting that many photos in one weekend you're doing something wrong.. the only scenario where I can imagine reasonably coming up with that many photos is motion photography with burst. Easiest rule I can give you is to pretend you have an old-style camera with a limited amount of rolls. Imagine how many rolls would be reasonable for the session you're having if it was 1980? If you stick to that, your photo quality will dramatically shoot up and the effort you have to expend sifting will go down a lot.
