I started riding when 1 bike was used for everything, my small zaskar frame with big forks always worked well. As long as you are having fun on whatever bike you have who cares? If your bike choice lessens the enjoyment of a ride it's time to add to the collection
Crashing is also fun if you can manage it properly. It's good to feel right on the edge of the bike's capabilities as often as possible.
Definitely over-biked at the moment, but sometimes you need something to slow you down on the hills. I have found that for a lot of what I ride a lighter, less bouncy bike is just as quick though, I just need to own one….
