The closest I have come to an 'exotic' bike like that was a Balfa BB7… It shared the same high pivot characteristics that you described - hard to manual, glued to the ground… But for what it was designed for the BB7 was a fantastic bike (cornering was very impressive), and in those instances when you got it in the air it flew straight [HTML_REMOVED] true…
I imagine this bike rocks in the Park, but leaves a little something to be desired on the Shore (although that high bb may be advantageous and offset the length). Is this your only ride or do you have another bike for general duty? It was the single discipline nature of the BB7 that forced me to sell it for a more 'do everything' design at a time when 2 dualies was out of the question for me.
