Who has it and how is it?

any issues once your climb the learning curve?

lets see some pics.......

 

I have one. Some things you have to learn include:

(1) Starts can be tricky depending upon your pedal setup and (in my case) when the bike is cold.
(2) Reacting to emergency situations in "car mode", not "bike mode" where you're grabbing for a clutch handle that is no longer there.
(3) Keeping the right foot down and left foot up at stop lights, or popping the bike into neutral as you coast to a stop.
(4) Not putting your left foot down on left hand u-turns.
(5) Getting a lot of comments. I was on my way to work last Wednesday when a bus driver pulled up alongside and said, "Hey, you must be that hand-shift Sporty rider my biker buds told me about...very cool!"

I also run a behind the leg shifter when I want something different.

 

You forgot hills....stopping on them is a bitch regardless of how used to it you are, lol. They're awesome, I've ridden a few different bikes with a few different versions. They do require a lot of focus and above all else a lot of PRACTICE, but if you get the hang of it, it's just damn cool. Be safe! And if you run a jockey, be SAFER!

 

yeah my thought is that the cool factor out weighs any potential down side
