Might be a close race...a good friend of mine's dad just picked up his shelby gt500kr today. it should go nicely with his 2 shelby gt500's. we were just playing poker this evening and i havent told him i ordered an IS F yet, or if he knows what they are.
i'll challenge one of his gt500's first. it might be interesting to see what would happen.
most likely i think i would need some power adders, but he has to work a manual, whereas i will only have to work 2 paddles.
