thanks for posting the pictures Dub-Se7en, never seen one like that before myself.... im just interested in the background regarding these blocks, so I email everyone trying to find out a little, hope you find it as interesting a subject as I do

Out of curiousity do they weigh a great deal more than the non-liner blocks ?

are there any other visual differences you note ?

Im curious as to what made you purchase them in such number are you in the performance industry or is there another reason ?

sorry but im a curious kid
