JL,


Could be one of three things.

One, poor action of the bag. I'll trust you inflated it but didn't over-inflate it. A decent bag, even if slightly under0inflated, will have at least 3 rebounds in it if hit solidly. A cheap bag, even if sufficiently inflated, will have poor action.

2. I hate to rain on your parade, but if you bought a bag and platform from a super store like KMart, the platform itself simply might not have very good action. does the platform itself vibrate when the bag hits it? If so, there isn't sufficient foundation to get good action. If it's a cheap platform, you have to minimize vibrations any way you can.

3. Swivel, but I doubt this is the problem. A cheap swivel will be, at the least, slower, but not slow enough to kill your action. However, a cheap swivel could affect the trueness of the rebound, a problem I talked about last week.

Here's my platform. Notice, it's thick...almost 2" like pro pltforms. It's also anchored to a steel i-beam. It doesn't vibrate WHATSOEVER when using it, no matter how hard I hit the bag. The 1/2" carriage bolts play a factor in this too.

In fact, I can actually hang all my body weight off this thing. You can't even do that with an $800 unit.
