Jaytea, you have a gorgeous system, I just looked at it! But God spare us MF. You can get more, and more accurate, hands-on information right here in these forums. (It's 4mm/degree BTW, not 3mm ;--)

As for the SME IV or V, you can't adjust SRA/VTA on the fly anyway. So basically, you HAVE to set it and forget it, which I therefore accept. HOWEVER, all the more reason to do so with the utmost accuracy -- for which you will need the adjustment screw and a set of automotive feeler guages. (The adjustment screw is removed when setup is complete, BTW)
