Shawn: It has been a while but they used to be different. In fact, one of the early problems AD had with the Lites was that they, compared to themselves, were very inconsistent...and yes, I spined them myself. I had them vary amongst themselves by as much as 30#. They may have solved that problem now but I just sold a buch of Trad Heavies to Guru and even they had two distinct spine groups....which I found to be embarrassing...but you need to be careful with AD shafts when it comes to spines and any of them that are "aimed" at the traditional archers.
