Awesome info guys.
Peakman- I am looking forward to someone whith the info you need, maybe Tony will come on to get you that info if no one else posts an answer.
JPH- Thanks a lot for that point about different durometer readings for different manufacturers. Do you know of any other differences? Say for T.M. to Jaco to TRC for Purples, Grays, Blacks, and Magenta (dbl pink for Jaco) and if so would you post that information?
If anyone else knows of this or anything else please let us all know.
