I'd take the 600 BUT I'm not sure if I'd want the vertical or horizontal. I would have to get some advice from the axiomites around here.

Then I would have to upgrade my CC (vp 150)and probably my fronts....... ahhh yes M60 rears and M80 fronts.......

of course I would have to wait to see the new products coming this fall.......

I better have my morning coffee now... dream time is over
