I am currently having an off line conversation with a Baller who is trying to decide what ski to buy. He has narrowed his choice to the brand and shape but he is confused about materials.
My 2 cents is as follows but there are plenty of Ballers who are engineers who can give even better answers.
Generally when a ski company makes multiple versions of the same ski but with different materials the “static” flex is about the same. The biggest differences are how fast the ski rebounds and the weight of the ski.
In my experience a heavier / lower spec skis may feel better from the wakes to the ball but never feel as good from the ball to the wakes. Unless the cost is out of your range I always tell skiers to get the highest spec version on a ski. No one regrets getting the all carbon & lightest core version of any ski (until their wife sees the credit card bill).
Not sure how to deal with a long link?
