Apparently Shimano had not given the rep a charger for his battery and so the battery was dying, but it still managed to shift the FD from the small to large ring under full pressure just fine. The rear derailleur shifted perfectly and so smooth, sometimes I would have to look underneath me to see if it actually did shift to a different cog.
I like to think SRAM has one of the fastest shifting Shifter/RD combos, but after playing with this, I think its safe to say that Di2 shifts faster and smoother than anything on the market. Not to mention the little effort required to push or tap the lever buttons. The cool thing about the front derailleur is that it automatically trims itself to match your chainline no matter what cog in the rear you're on. Having a FD that doesn't rub is just amazing.
