Gift for Wife-

But since i assume youre trying to keep it a secret and probably cant have her come here to ask herself (much better) then the SAFEST bet might be a hybrid camber.

The reason i say this is because if her board is 7 year old there is a very very big (certain) chance its a camber ride. Which means a hybrid would give her more options to play with. 

It sounds like, (reading between the lines), that you guys are just up for riding the resort and having a blast and not really looking for riding exclusively towards one sphere of the resort/back country. So yeah, stick with something similar flex to what your wife already has unless she has openly stated she wants something different in flex. Switching from camber to hybrid/rocker is a big change in itself for lots of riders, so you dont need to tweak too many things on top of it. A camber ride and a hybrid ride with the same flex are still going to feel pretty different. The hybrid will still feel looser and more playful, and the camber will still feel pretty tight and on point (assuming the size of the board is pretty much in proportion to her weight). 

So if shes looking to replace it and er, upgrade (arguable term :)), then something similar but with a few tweaks will make her day. If on the other hand shes looking for something uttely different or a jib ride or a powder ride, then youre looking for a very specific type of board. 

As i say though, it seems (between the lines), its just an all round board, in which case a soft-medium flex hybrid might be a lot of fun for her. 

So thats my advice. Im afraid youre gonna have to do a spot of research now to figure out what boards fit the bill and which ones are in your price range and what you want to pick up. Best thing is obviously to get her to tell you, but yeah, if its a present that might not be an option. 

Good luck dude. When you have a shortlist maybe post up in the actual forums so that you can get a range of opinions on them. 

camber: poppy, stable, may feel stiffer than shes used to on a comparative flex, but assuming the board isnt infinite ride (feels the same out the box as day 100), it will break in. 

Reverse camber: loose, bouncy more than poppy, catch free (sorta), comfy but lacking a bit of bite to it. generally versatile, but may have issues with stability whilst simultaneously saving you from scorpions every now and again. Probably going to wash on an inexperienced rider unless its got effective edge out of its ears. But then again, going to help inexperienced riders get comfy riding AND also give experienced riders used to camber a radically different (and more buttery/playful) feel. 

Hybrid1 : Mix of the two. Got contact points for more stability, a bit of camber for a bit of snap and a nice loose feeling with a bit of weight shifting to the back. Best of all worlds with all the benefits of camber and rocker, and also the worst of all worlds with none of the benefits of camber and rocker depending on what youd prefer.  

Hybrid2: Camber between inserts (and more often than not extending as far as possible outside them), with raised contacts. I guess, (what else can i do having never ridden one :)), its supposed to be snappy like camber with a good ability to load it, but has no contacts for a bit of a loose feel. 

Hybrid 3; Multiple cambers. Weird one this, but generally reverse camber in the nose, and flat or standard camber moving to the tail. Its directional and people have a fit about directional, but not me. I kinda love it. 

Flat/zero camber: Always been intrigued by this. A few years ago was written off as dead camber. That is, camber thats lost its snap after a few seasons riding it. But theres so much tech out there for tweaking performance its recently made a resurgence. If i understand it all correctly, (and i dont necessarily) flat is to camber what maybe camrock is to reverse. A kind of tweak to soften up its extremities. Its still got the camber feel but it will likely also feels buttery and playful. 

Sorry if thats a bit much when you probably just want a recommendation, but thats what i gots for ya. Understand theyre all generalities though. Every board has way the hell more going on than just its camber profile and this will all work together to define the ride far more than just the camber would. This just kinda gives you a very general simplification. And this simplification is often through common sense and not in fact expereince. For that youll need to garner more opinion and i would therefore strongly recommend you pop into the main forums and ask your questions once you have a kind of shortlist. :)
