Best of both worlds

I recently got a Revolution bag and love it! I also have a backpack bag that I have been using since 01. I would suggest you try them out/on b4 buying. I'm a big guy so the backpack bag rides a little high on my back for my liking. I do however use it to carry extra discs, towels, rain geer, shoes and anything I could possible need for a weekend. I also have a tour bag that has been to hell and back and held up nicely. Things I like about the revolution: mombo zippers, rain flap, zipper flap and padded back.
Things I like about the tour bag: two water bottle holders, plenty of room and Dave listens to the feedback on the bags and upgrades the bags often.
Take a good look at both of them and decide what matches your needs best. One thing I learned about both companies is they stand behind the product. Talk nice to Dave Mac and he's good about adding a little something extra!
