I haven' t surfed the elf or hf so I can't say how much the cc would help you "push" your surfing in comparison to those boards. The tail is obviously different. Chris or Paulnunn may be better people to field that question. I can say that the cc has perfomed excellent for me in waist to head1/2 + waves. AM1s, WCT, and EA techflex-for overhead surf). At 180lbs and 6'3 I feel that the 6'1 cc fits me perfectly. If I could swap for another size, i'd get the same 6'1 every time. At 180lbs you can go smaller but being 6'3 I need a bit extra length. That's still riding a high performance board that's 2" shorter than me. I can't wait to surf it*again!! I'm so obsessed with the board I still come back to this forum when im not in the water.
