I borrowed the prototype Vibe in Feb on the GC. Rode it in knee high glassy Greenmount, head high good Currumbin, and head high howling NE Broadbeach. It was fine in all those conditions. Gotta ride it like a shortboard fish...getting down low... Larry Bertlemann style... turning around the extended paddle. That 8' Coreban was fast, fun, and stable.
