Happy why are you posting a relevent post here? LOL I would say in a non-track situation there is no reason to go with cross drilled and vented. I personally never had a cross drilled rotor crack but have seen pics of full race rotos cracking in dirt track racing under very extreme conditions. i.e. frequent full brake applies with short cooling times.
