I weight, but I do not know what would be the best. Here I bow flex-Select-tech are very large and that on the road, but I've also heard that the bars around the handle of the Power Block Pro on the road. Also that you can change the weight of the weight faster.

If any other type of weight that is better than these two that I can find.
