I've got a PF/SF that started with 13 WE (Black). It's taken 3 seasons for him to get to get to 28 WE (Black). In season he's had +33, +43, and +53 in TOT jumps. But that's with 22-25 MINs and he always comes back the next season minus a few points (3-6).
With a 2WE I'd be worried about him deteriorating over the offseason. Too much xbox and mt. dew.
