We sell a bunch of both the Heritage and the Gold Tips. The Gold Tips certainly win out as far as quantity sales ...2014 CX 500+ dz and Gold Tip 4500+ dz sold. Sales isn't always a determining factor though.
More people seem to have difficulty with feather, wrap, and insert adhesion with the CX heritage, but once you have that part figure out, there isn't much difficulty.
I would say that the Heritage has a slight edge in durability but I personally shoot the Gold Tips as I find them to be very durable and easier to tune...having said that, I find the Heritage tune better out of my personal recurve...it's all about the right spine for your set up.
I hear people ask about the consistency of this and that, but they all fall within the specs set forth by AMO and are far more consistent than wood.
In reality, the only way we have to measure spine consistency is "static" and the small discrepancies found have little if any affect on "dynamic" spine.
There are so many things that affect how an arrow leaves the bow and the number one most consistent one is the individual bow...number two is the arrow. Too often the equipment catches hell for the faults of the driver.
I have some beautiful footed wood shafts that I like to shoot from one of my bows. When I quit worrying about how straight they were, my groupings and accuracy improved greatly. I don't ever look at the straightness anymore and boy they shoot great.
I think I could remove a cork with at least two of them though.
