What CAM would be the best for me? I mostly just ride on the MX tracks but I also go to the dunes to drag. What cam would work the best. Also I don't hardly ever lug the bike, I am always in the higher RPM range.

I forgot to post that I will have the MARCUMs 416 kit with a 10.8:1 compression piston. With the the head ported polished, oversized valves and 3 angle valve job done with the stiffer valve springs.

The TC is a bottom end cam, so while it is good, it probably isn't for you. The xr cam is a great cam, but it is still a "stock" cam (I am happy with mine, but will probably change it in the coming months). If the rest all have the same specs, buy the cheapest one (I am thinking about the web 451. At least I think that is the grind #).

TC has a XC and a MX Cam. The XC Cam is for all Bottom End and the MX Cam adds Power all around which is what you want for MX.

i think that two of Web's cams are kinda mild...then the one that i said is a definite high performance cam....

I forget who original posted it but great info so I copied and saved it. I am waiting an HRC copy from xr's only. It cost about half the price of an HRC, and the same grind. It is also a drop in no hardening of the rockers.
