Well did you make the switch
I did. I purchased my F6B exactly 1yr ago with a Mustange seat. Bike had 8k on the clock, now 13k. I'm not much on the padding on my back side either so the Mustange was really bothering me after just 100 miles in a ride. 5'11 - 180. I just found an Ultimate King that was only 1year old and not used much from Mike, a rider in TN. He ordered a RDL. I bought w/ shipping for $500. I rode to S GA (Hahira) and back Milton, FL this past weekend and loved the seat, Great ride I might add. I have the same seat on my Valkyrie and figured I would like this on my F6B.
I'm loving life.
