In addition to wheeling their Toyota Camrys in the NASCAR Sprint Cup Series, Busch and Hamlin also will be racing Tundra pickup trucks for Billy Ballew Racing in Saturday's Kroger 250 NASCAR Craftsman Truck Series race at the Virginia oval.

Busch, who leads both the NCTS and Sprint Cup points, will drive Ballew's No. 51 Tundra, while Hamlin will drive the No. 15 Ballew entry, which for the first time this season also will be a Toyota. Previously, the team had run the No. 15 as a Chevrolet Silverado.

The two JGR regulars are hoping that the double duty in the Truck Series will pay dividends, especially on Sunday.

"I think running in the truck race is always valuable for us in the Cup race on Sunday," said Hamlin, a Virginia native. "The new Cup car and the Craftsman trucks are very similar in the draft. On the competition side, it will be valuable for both Kyle and me as we can learn a lot on pit strategy and the draft with a vehicle that doesn't turn real well like the trucks because of its long wheelbase. It should be a lot of fun mixing it up out there and I hope to walk away with a solid finish and valuable information for Sunday."

For Busch, who has been the sensation of NASCAR so far in 2008 for his performances in all three of its top series, Martinsville frankly isn't one of his favorite tracks. He's hoping that the extra seat time he'll pick up on Saturday will benefit him on Sunday.

"This isn't one of my best tracks in the Truck Series," Busch said. "We've come out of here with some good finishes but those were just luck, I guess. We want to make sure we have a better handling truck so we can come through the field in order to get to the front and make some passes. This race anyway is always a tough race because there is only like one stop and you have to have a good handling truck for a long, long period of time. So being able to work on that is going to be a big key to our success here when we come back."

Like many of his peers, Busch has found the 0.526-mile flat Martinsville oval to be deceptively difficult to navigate quickly and consistently.

"It is a tough little particular racetrack," Busch said. "There is a certain way to run this place and there is a certain way to get into the corners, go thru the center of the corner and come off the corner. For me, I've been able to figure a little bit of that out but not exactly all of the keys that I need to win here. I haven't had a win here yet but I've had some strong runs. It's a good track for me, it's just something I run well at, but you know don't put me in your fantasy picks to win the thing."

For Hamlin and Busch, racing on Saturday also gives the two a chance for some old school bragging rights and chest thumping. "Kyle and I are friends on and off the track and we've already started trash-talking about the race," said Hamlin. "Hopefully we'll be able to race around each other out there and bring home a truck series victory for Billy Ballew."
