Ive yet to try any of the 601 stuff.. but at those prices I think a box of oscuros or maduros might be in my future..
I have some 3 year old greens that are still a harsh kick in the mouth. The blues and reds are head and shoulders above the rest, IMO.
Edit - and if you don't get some this time, I wouldn't worry. For some reason (maybe they don't actually sell that well, I don't know), a store somewhere will usually discount the crap out of them for around $75-$80/box every once in a while. Atlantic does it fairly often. Cigar Place just sold out of reds and greens for $65/box that were all a couple years old.
