I thought 2010 was the last year before the Cult ceased to exist?
Anyway... with a kite that new, I'm not sure I would bother upgrading just yet unless you really feel the need to. At your level, the Cult will do all and more you ask of it. Sure, if you need a smaller or larger kite go for it.
Board wise, if you like Nobile (I do), but you want more rocker and less spray, consider the NHP. Virtually no spray, and more rocker on the board makes landing those tentative first boost n'pop moves so much easier
