The non metal SG (Full Carve) is a fantastic board. I own a titanal 163 from 2011. It is noticeable at high angles the Full Carve has less torsional stiffness. For my perception, the Full Carve is around 90% of the performance of the Full Race Titan. It does get going at lower speeds than the FRT, which means that it produces a pleasant ride at lower speeds. Subjectively I would say that the Full Carve is more juicy. I would strongly consider to get the Full Carve next time round, irrespective of the price.
Its big, Its really big. It doesn't take a brain surgeon to tell that this is highly exposed, way out of the the box, you know... out there, kinda stuff...
