XC and a light DH/freeride or just one good all mountain bike?

I am riding a '07 Santa Cruz Superlight, I love it's acceleration, speed and its ability to climb but when the drops get scary I feel like I could do with something a bit more (plus I would really like to jump a little).

So the question is (and assuming I stuck with Santa Cruz and cash no object): should I trade my Superlight for something a bit more all round like a Blur LT or a Nomad - or keep the SL and go for something like a Bullet as well - or just get better on the SL
