I've had my 08 SD for a few months now and love it. As said before the 1st gear is quite high and combined with the V twin torque shudder at low revs can feel a little aggresive on take off however give it more revs and a smooth lever action and it is not a problem at all. The SD is not like a jap bike that you can ride along sedately and expect a quiet smooth ride, it will punish you, but actually RIDE the bike with enthusiasm and it will reward you .. you wont get the grin off your face!.
I have the KTM touring screen and dont mind the look of it at all, it takes some of the wind off the chest area and still pretty buffet free over the helmet if you sit fairly upright ( I'm 5'9), if i lean foward to balance the wind draft at over 120 kmh or about 70 mph i think, then there is a little helmet buffeting, but they are pretty cheap and you can swap them in five miutes so give it a try.
Good luck
