Just ordered a 130lb banana bag to replace my current free standing bag that I broke. I spoke with Neil over at KO fightgear, and let me tell you, this guy is the most sincere individual you will ever meet! I was very impressed with his knowledge on the subject and the fact that he actually goes beyond the sale to educate his customers on what they're buying and how it is made. This is the kind of integrity based service one should expect from all businesses, but unfortunately it is few and far between. The bag itself I have obviously not received yet, but I'll continue this thread with a review when I do. So before you guys go and buy and brand name that isn't filled, or one that's filled with sand or whatever...give Neil a call over at fightgear first and have a conversation about what it takes to make a good heavy bag.
