I am new here, and I am considering purchasing a the medium satchel from Saddleback Leather. Just wanted to see if anyone had any experience with the bag or any other saddleback shoulder bags? I have read that the weight is really the only negative to the bags. Any input would greatly help! I currently use a red oxx rock hopper daily, and while it is a great bag, I have plans to sell it and purchase a more professional bag for work. Thanks!
