Dear All,

I would like to hear what breaking material you use / prefer for power demonstrations... wood (white pine , industrial yellow pine), patio blocks, roofing tiles, ect.

Also, I am wondering if anyone has done any density comparisons between industrial yellow pine and white pine (traditional breaking material)! If you have broken both (or even held a peice of each) you will certainly agree that the "yellow" is much harder.
What in your personal experience would you say is an equivalent equation?

1 (1x12x12 yellow pine) = ? (1x12x12 white pine)...

I have told someone on this forum that I feel 1 peice of yellow is almost equal to 2 peices of white...I believe that this comment was maybe a little over calculated (but not much)!

Looking for some input!!!!!!!!!!

TAEKWON!
