If you want an MV go with the 1000cc.
I also have an F4 1000 and love it to death
I had an accident back in November last year and a few moths ago i decided to put my MV up again. The bike got ready this last weekend and i went for a ride.
WOW!!! I love the handling and power of the MV
Yeah, it has a more radical and racy position than the Duc, but to be honest i like that.
Also if you're the tall guy like in you avatar, you won't have a problem with the higher riding positon of the MV
