Your only going to go so fast with an Eddie or a pro comp, no matter which you use. No way I would go with the inferior casting quality of a pro comp for something that going to be driven on the street a lot. Eddie is a known good, long term reliable head, same is far from having been proven with the procomp.
As sad is it is to say Don the pro comp that I did back to back with E - heads I was doing at same time pro comp was nicer head.......
