FYI.. I have a set of Gen 3 heads, perfect for the Greg Good upgrade. Matter of fact, Greg and I fought to get them from the same source. (I Won) ;-)
I have since decided that putting gen 3 heads on a gen 2 might be too much trouble given the marginal gains possible from the better gen 3 heads. So if anyone wants a great set of Gen 3 heads perfect for being sent to Greg Good for upgrades. Let me know.

PS. That reminds me, I should just start my own post ;-) thx.
