I like the change, regardless of the short term impact on the "show".
When you get right down to it, it's the one change that applies 100% evenly to each and every team out there. Any changes made to compression, blower overdrive, header angle, mags, fuel volume, nitro percentage, or what have you, gives an advantage, however slight, to the well funded teams because they can generally afford those changes immediately. But by reducing traction, it forces everyone to figure out how to get from A to B with what they have. As Ace said in the link provided by Alan, however, it may eventually lead to more innovation which once again probably gives an edge to the high dollar teams. But in the short term, the playing field has been evened out and once the crew chiefs figure it out - and they always figure it out - we should have some fantastic side-by-side racing.
