What is your intended purpose for the bag?
I have a nylon Gamechanger and a waxed canvas Shmedium bag, and a few others as well. But after 4 years, I have found the Shmedium to be the most versatile and useful. Remove 1.5 cups of the sand fill, since it has a spout. I have found that to provide the best overall performance, from cattle gates, to rocks to rear bag use.Not having seen either in the flesh, I am looking at buying one or the other but do not understand why someone would pick one over the other. Can you give me the pros and cons of each, or some other comparison?
