    Its a work in progress. Im picking up lunch right now before I get the thread links all named so you dont need to click through everything to see what it is.

    I dont have an ultra that I do maintenance on regularly enough to write a troubleshooting guide for like I did for the 15f but I can compile stuff together in a thread if yall help me out.

    Heard and read a lot about the late Skip Holmes,he wasn't afraid to "push the envelope" on this ski in its early days..

    He wasn't afraid to fail and come back to make it right!
