Scotty Cameron swingweights??

I was wondering where I could get additional swingweights for the Scotty's??  I have a Newport 2, 33" and would like to tinker with the swingweight and see if it makes much difference .... i.e. on slower greens (which I tend to be on more often than not). 

Any help or insight would be greatly appreciated.

This is a recent addition to the Scotty Cameron Studio Store under Cameron Creations:  It is a Sole weight kit along with a removal tool:  http://www.scottycameron.com/webstore/do/products/cameroncreations
