There's nowhere as demanding as Hawaii -- it can break your body and your boards, and that's why the pros are turning up on the North Shore with dozens in their quiver.

While they may bring as few as six to another Championship Tour location, Hawaii forces them to be especially prepared for a variety of conditions and the chance they could break several in a single session.

As Leonardo Fioravanti explains in his latest Vlog, one day you could be riding a 5'10 and the next, you could be out at Waimea on a 9'6.

Leo shows us that the volume in his Arakawa boards's are pushed forward "which basically lets [him] ride a 6'4 when waves are quite solid while back in the day people would be riding 6'10''s or 7'4''s". Forward volume is a crucial design aspect of surfboards when it comes to achieving paddle power to get you over heavy ledges.

Here's the run down, Leo has 30 boards in Hawaii right now. For the most part Leo rides Christiaan Bradley Surfboards but when he comes to the North Shore, Leo experiments with boards from Eric Arakawa. For Leo's surf off against Mikey Wright, Leo rode 3 different boards in the 3 heats. The first heat which Leo lost 11.54 to 11.33, he was on a 6'4'' x 18.75" x 2.48" 30.2 liter Arakawa. In the second heat Leo won 9.17 to 8.97 riding a 6'6'' x 18.75" x 2.48" 31L and finally Leo took that last spot on tour riding a 6'2'' x 18.75" x 2.43 Christian Bradley beating Mikey 14.00 to 8.57.

At the 7 Minute mark Leo links up with his childhood friend Jack Robinson and they both shred Sunset on some 6'6''s.

Take notes on equipment and style as the two phenoms drop knowledge and hammers.
