will only regret it if you dont get the Sv1000N
can do all the stuff that you can with a faired. sustained high speed can be hard work though.
TBH i prefer it. had a hornet, traded for CBR600f, got another hornet. the seating positions on Nakeds are more upright and the bars are wider. this means that you can throw them about more!
also think they are more exhilarating because you can feel the wind balst and arent cocooned behind plastic. On the downside you are exposed to more of the weather!
