re: favorite bag?

I have a Callaway Chev bag. I walk about 90 rounds a year. I love it, meets my needs perfectly. My only issue is the stand. If I set my bag in the garage, smooth concrete floor, or on the wood flooring in my house the legs will "do the splits" over time and my bag will fall to the floor. I do not know if that is a flaw with this particular bag or if that happens with any stand bag resting in a smooth surface. If not for that the bag is perfect. Simple solution is to set the legs on a rug or mat so there is some grip.
