Thank you both for the information. Its seems as though the Mag risers are not much different than the wood ones.
I found the following information, but don't know how accurate it is.
Dymondwood A riser 1.8 lbs
wood A riser 1.5 lbs
Dymondwood B-riser 2.25lbs
Thank you once again, I appreciate the effort you took to give me the information.
