Well that was unexpected, bit sensitive...
If you buy a bike built for pure speed and give away 12 easy Watts, that's ~15 secs per 10 mile the competition is gaining on you! One of the biggest differentiating factors between the latest super bikes and standard bikes (such as the Slice) is actually the integrated bars, not the fancy features like hidden brakes etc. You can close the gap between superbike and standard bike to be very narrow by selecting a set of good bars and running the cables neatly. The stock base bar and clip-on setup probably costing you lot more time in terms of position too through lack of adjust ability.
Btw, IIRC you are also voiding the warranty running the stem like that.
