There's no one even saying wow I've gained x mph. Would you ever buy something because the producer says hey I can't prove it but " you can feel the difference" no thanks. Prove me wrong and please set
    People straight about your ski before more rumors are spread.

    I have a feeling most of the people you are trying to prove yourself to have no idea what those numbers mean. LOL

    Can I just ask what may be a dumb question- if its done by hand, how are you sure that you are porting each one of the cylinders evenly? That was what I never got...
    NO criticism. Just an honest question from someone who has a limited knowledge of portwork. Dont some machinists write programs and do it with a CNC machine?

    i have special gauges and tooling to measure each runner, and bowl area to make sure im exact on each side. Sure you can pay $1000+ for JUST a port job *IF* someone has already written a program. For you to bring a head to a machine shop who is capable of CNC porting a head isnt going to just charge you to port the head, you will be paying for the machinist to sit for hours and write a program, then port the head. Unless you are planning on doing a ton of these heads, you will have to settle for a hand portwork.
