So what is best for a beginner/learning? Easiest to learn on?
Rocker or Flat with lifted contact points are likely the two easiest profiles in terms of the first few days of riding. BUT, as with all things in design, if you get something, you give something. They are initially easier because the contact points and much of the running surface has been lifted. Those surfaces are less available to the rider as they progress. That is great for some types of riding and less advantageous for others. Please note that most riders get through the part of the learning curve where this is a major issue in a matter of a few days, so they are really better advised to rent during that period and then buy a board based on the type of riding they want to do.
