hmmm, there's a world of difference between the Twins and Fours. Your first post you said you loved the high rpm revs; you won't get that on a Twin, the power builds pretty steady (on my VTR anyway) from down low to about 10.5k rpms. You get butt-stomping torque as opposed to a Four's rocket thrust at high rpms. It's a differnce- if you like hyper, screaming engines, you probably won't get into a Twin as much, IMO. But if you have the chance, try it- you might like it
