After having tried a number of different bags this is hands down the best quality bag on the market. It even handles better. First, this Stong model measures 25" in length, while a competitors model is 29" in length. making the Strong model easier to handle. Also the way the grip handles are sewn flat as they meet the bag body, causes less resistance when spinning. The leather does make a difference when gripping, whereas the vinyl bag works best with liquid chalk. The carry bag this bag came with was as expertly made as the Bulgarian bag itself.I purchased this particular bag because I could change the weight. Which was simple enough to do. What may be a source of frustration is getting the bags expansion pouch zipped to secure the weight. Getting the zipper around the two corners could be near impossible for some people, but I found that Zipper and Snap Lube makes it a sinch!! Luckily, I keep it around my workshop. That would be the only suggestion I would make to the distributor. To supply a small packet of Zipper&Snap Lube or make the suggestion in the directions.
