I am going to say that you need to seriously evaluate your wants and desires. From what you have said so far, I think the big Ninja is going to be the bike you WANT.
If you go with the V, I am sure you will like it, but you might wind up with a little buyers remorse, and that niggling feeling that you should have bought the Ninja. You will likely pump a bunch of cash into the V in a relatively futile attempt to boost the power, and still not be anywhere near the rush of the Ninja.
That being that, if you can live without the massive HP rush from the Ninja, the V is an awesome all rounder, and has enough poop to keep a smile on your face.
