i want to know hjow good thewy hook up and if they hook up as good as race tires, and will the extra weight make my 300ex slower?

 

My friend has some mud sharks on his 400ex and they look sweet. Also last weekend there was a ton of mud in my trail and his quad was just blasting through it like nothing. So they hook up sick in mud. I was thinking about getting some for my lakota but dont know what to do.But they are a sweet tire.
