Graeme, you can talk until your blue in the face about whats good for the driver, but the only way you will get anywhere is to talk about whats good for the shop owner. Stacey has stated he is in favor of the MG yellows, but he is only one vote, the problem is with the kart shops over there. By the way, how is it going with the weight changing to 395# in the senior heavy class? last I looked the vote was heavy in your favor.
