Thanks for the Answers and opinions!

I was really leaning right now towards the William Joseph Surge lumber pack as I think the magnets are kinda cool, and I like the two camera pockets on the belt.

But the first one I was looking at was the Fishpond Waterdance guide. I really like the fishpond gear as they seem to have the most options and thought out. The Nimbus one looks awesome, but maybe a little too big. I don't carry more than 2 fly boxes with me ever.

The Simms Dry Creek looked like the most waterproof of the bunch. The thing is, I fish in rough weather, rain or shine. and I boldly wade some stuff. And when out on the flats, I've had the bottom of my sling bag get slapped when wading deeper than normal. I usually just put my wallet, cellphone, camera, and keys in a ziplock and dump it in the bag, but I just wasn't sure if there was a more sealed bag option.
