I got the Addidas 6 racquet (black w/white lettering) a few months ago and really like it. One of the reviewers commented on the advantage of a non racquet company logo, in case of switching racquets. I was drawn to that line of reasoning since I like to choose items that will keep options open. I'm glad I did, since I'm currently in love with the Dunlop Maxply McEnroe, instead of my Head fsp Heat.
The size of the bag is just right. Not too big, not to small. Comes with backpack straps, double handle straps, and removable shoulder strap. The only improvement I would like, would be some sort of dividers built into the center misc. pocket, so that balls, wallets, cell phones, keys, water bottles, etc., etc., etc., would not slide up and down in one huge pocket when you use the bag vertically with the backpack straps.
