Good Question RB. However, something else that needs to be considered is why would any given company come out with a hybrid design and yet still offer dual and single cams as well? Isn't the entire purpose of the hybrid design to offer many of the advantages of a dual and single cam without any, or many, of the disadvantages?

How would you market your dual and single cams if you just came out with a hybrid design?

I am genuinely curious.
