Good question,icebird! I think it depends on the size in this matter. Monk performs very well in the waves, the Supershinn shouldt be smoother then the Monk. But its a freestyle board all over. So enough pop, chop eater and no spray.
Speedball, totally different board. You will be better try the Supershinn. Red is a good board, you may outgrow it very fast. Supershinn is also good for a beginner.
