I've been looking for a slightly larger bag than the F-5Xb I use right now, which led me to these two. Problem is I don't have a local retailer that carries both, so I can't really compare them.
I usually use my bag to hold my lenses - three compartments for two lenses (third is on the camera) standing upright. When I'm only using one lens, I put my camera in on its side, grip facing up.
I decided a slightly larger bag would be better because 1) the -Xb looks like an equipment bag, and I think these look much less like one, and 2) I decided I might be better off using one larger bag rather than two smaller ones when transporting my stuff.
It'd be nice if I could use it to carry notebooks and pens or other "normal" stuff, too.
Any opinions?
On an aside, does anyone know where I can get older Crumpler bags? These new ones are ugly...
