I find that my Aelle framed Barecci is fairly stiff and predictable getting on down the road, but it is heavier than my SL framed bikes.
I like to say that my SL framed bikes are my sprinters, my nimble handlers, the ones I would take into a race, while my Aelle gives me a nice predictable, comfortable ride for the long haul. So for me, both are fine, but for different reasons...
