View how a Riley solid balsa classic board is shaped and later ridden by Barton Lynch and friends. First they take the 9 footers for a try-out and at the end Lynch rides the 12 foot one. Check out how it glides through the big flat section. I guess if you have a board like that you will see familiar breaks with different eyes. You can connect peaks that you regard as singular take-offs when taking a shorter, foam board. My favorite break would probably be very good the longest right in Europe with one of these.
