Your physical stature really falls right in the middle of either selecting a King or mid sized Ultimate seat. I agonized the longest over it. I finally chose the King because I wanted "wiggle room" while in the saddle and felt that the King was best for that. My metrics are 5'10" 215 pounds and inseam is 30"
I do have handlebar risers too but wish that my reach for the bars was still less. I just can't commit to buying those expensive Helibars with the possibility that they will not improve my reach. The throttle cables really concern me, they are already tight just with the handlebar risers.
