^^^ same.
I had Di2 bar-end shifters on the aero bars, then found the TT brake/lever Di2 shifters for cheap on eBay.
My "winter" bike only has the Di2 bar-end shifters...and I can't stand it. For sure, I use those at least 80% of the time, but for being able to quickly get to the right gear when standing up...that other 20% makes a huge difference!
Suffice to say, I'm scouring eBay looking for another cheapie set of 6871 or ST-9071.
