  1. Searchmont

    Anyone carving on Searchmont? Rain has decimated local bumps and looking for something different than Boyne or Nubs.
  2. Because the Nirvana was useless today. I moved the bindings back on my Coiler AM and had a blast.
  3. Rejoice, You have taken a major step forward.
  4. Visor Helmet

    Anyone using a Uvex Visor helmet or similar? How robust is the visor to fogging?
  5. N. CA Not Looking Good!

    The Jet Stream has been serving up that area every time I check.

    Its the Jet Stream. Our flights to Denver scheduled for tomorrow are cancelled due to up to 12" from Milwaukee to Buffalo. And this is a simple 10 hour drive to the west end of the UP.
  7. Official/Unofficial ATC 2018 thread

    MyRadar is forecasting 6" from Snowmass Village across to Aspen Mountain. It's being feed from off of the NW coast. Post your actual total to validate their forecast.
  8. I can’t believe the end is on the Horizon (6 weeks at best in MI). I have spent more time researching the weather than anything else so far. Are you banking the stoke for the pending offseason? Are you achieving your goals? Don't put it off, the actuary tables are unyielding.
  9. Carved turn based on edge pressure, right?

    May the Stoke be with you...

    I remember it different. Watch out for the web cams!
  11. For lack of a better description I will name the knee fatigue “nervous knee”. Although I agree with the sequence of events I do not agree that rider input is the root cause of a nervous knee. There are only two ways to solve a problem: 1) reduce input variation 2) become robust to the input variation. Following your train of thought, if a riders’ poor technique was the root cause of a nervous knee then the introduction of a damping device is a robustness action if the poor technique cannot be cured (reduction of input variation). The damping device mitigates the poor inputs resulting from the poor technique and thereby prevents the establishment of feedback signals to the knee that cause the nervous reaction. Consider the following decision matrix: If the riders’ input is indeed the root cause then the end result of an uncomfortable nervous knee is independent of the surface. The nervous knee is a function of “poor technique” rider input generating an undesirable feedback signal resulting in a nervous knee leading to fatigue. Conclusion: A “Poor Technique” rider should expect a nervous knee under all surface conditions even when riding a generous layer of forgiving powder AND a “Good Technique” rider would never welcome relief on a hard lumpy/uneven surface. Not convinced either If the surface condition is the root cause then the end result of an uncomfortable nervous knee is independent of the technique. The nervous knee is a function of the surface condition generating an undesirable feedback signal resulting in a nervous knee leading to fatigue. Conclusion: Both a “Good Technique” and a “Poor Technique” rider would benefit from a dampening device when riding “Hard Lumpy/uneven” surface conditions. In both scenario’s the damping device is a robustness action against the poor surface condition. Reality Check: There is a strong interaction between Technique and Surface Condition but I would argue that the overwhelming driving force for a dampening device is not to overcome poor technique induced nervous knee reaction but rather the desire to ride beyond optimal conditions.
  12. From a system interface perspective the resilient pads act as a robustness measure against the board/surface interface variability. The board/surface input variability driven back to the knees is the feedback to the rider to back off until the noise settles down to a comfortable level or employ a device to dampen the signal and charge ahead. While I agree that improper form could lead to an uncomfortable ride it reads that while riding they are in active use during which snow would certainly shear before sending a signal back up through the bindings. That leaves a hard uneven surface as a probable root cause of discomfort and thus the utility of the pads. The input error is at the board/surface interface.
  13. Coiler Nirvana first 1-2 hours when the hill is empty...Coiler AM to play pinball for the rest of the day.
