The 2014 Deluxe shape is the same as the 2013 Peak Shape. So you can always stick with the same shape. Raph's board is said to be a mix between the 2013 Peak and 2013 FLX.
2013 Peak- CNC Wood PU Core, Center concave, Triax Glass.
2014 Peak- All Wood Core, Thinner profile, Lighter, Responsive Flex, New Rail Edge, Different Biax Glass weave provides the proper spring & snappy flex.
2014 Raph- Same Core as Peak- CNC Wood PU Core, 3 stringers.
I haven't ridden any yet, but most pro riders right now that rode the Peak Last year are on the Deluxe this year, might not have had the chance to really give the New 2014 Peak or Raph a fair shot yet as they are still in Competition Mode for the remaining contest.
Best suggestion would be to try all of them out, hopefully your local shop has some Demos. If not try and get to a Demo or Liquid Force Free For All next Spring to try them out!
