I recently checked out SWM's clamping info. CD. The information it contains is very straight-forward and gives you a clear idea of...
*Where to buy cable clamps and how much they cost
*The best material to wrap the penis with
*How to apply a clamp
*The two most effective exercises, and his technique with each
*How to double-clamp
The information can be found in text descriptions on the internet forums, but sadly there is no video or audio guidance. SWM's CD provides those who find it difficult to follow text descriptions a thorough aide. If you are an advanced clamper, you likely would not benefit a whole lot from this tutorial. I can vouch for the exercises covered in his CD, that they have been the most beneficial clamping exercises that I have utilized.
