When I read the question I thought the same thing kind of like the ford /chevy question,, I always go up and have stayed that way, it works for me,,but I have read arguments on both sides and see the point on doing it the both ways,,
With that being said I would love to know what you find out when you compare both ways,, but the hard part about comparing is all meats are not created the same..
let us know..
