The Professional Ski Instructors of America and American Association of Snowboard Instructors (PSIA-AASI) produce 32 Degrees, a beautiful, incredibly informative magazine for their members and partners. And the latest issue features a phenomenal article titled, “All Rocker Isn’t Created Equal,” by ski instruction legend Mike Porter.

This really is a must-read for just about anyone interested in ski and snowboard technology, with a series of charts that shop kids might want to consider printing out and posting on the tuning bench wall. “How Do You Decide What to Ride?” covers the snowboard side of things from the viewpoint of AASI Snowboard Team Eric Rolls. Here is a link to the PSIA-AASI SnowPros page, where you can access the article preview with links to the PDFs.
