on a side note, the cracking you hear when you flex skis is not a problem. think about how many times your ski flexes with your whole weight on it when you ski. thousands of times a season. don't worry about the cracking sound, new skis just do it.
my level of radness... it just can't... be quantified.
The butter zone is the part of the Invader that is milled the thinnest. This makes it flex like a hinge, allowing for easy buttering when the ski is flat. The torsinal rigidity of the ski gives it a more traditional flex when you are up on you're edge carving a turn.
So the wood in the middle is milled thinner at one point at the bottom and bottom of the ski but does that therefore mean the ski is more likely to break at that point because that is the weakest part of the ski. To cap it off, by making the Butter Zone skiers are encouraged to bend the ski at the weakest point. Sounds daft.
I would like to know how Aramada make the Tanners so flexible at the tip/tail.
^ yea pretty much thats what it is, A thinner spot in the core, also, wood and fiberglass are very flexible materials, line does not have magic at all, they haven't even figured out how to do cap construction properly yet
