In future i will stay out of this debate as obviously there are alot of opinions out there on this topic and i have only been racing 12 months and dont have enough expirience. I was only going on what i had been told before on the MTX-3 thread and after putting into practise what was said there it worked and that was "C" Blocks have the most traction and "A" blocks the least and after seeing what setup's guys had that ran on high traction tracks versus low traction tracks, it seems that the faster guys in Australia use the B and C blocks for med to low traction tracks and the A block for higher tracton tracks.
So in conclusion i am sorry if i upset anyone on here but i think in future people who are asking the question on this topic should just do some research for themselves to save the differences of opinion and the arguments.
