I have no idea why you insist on arguing with all of us. I gave my opinion of how hydraulic discs on my heavy loaded bikes and clipless pedals perform for me; it was not a technical argument. If you prefer calipers and standard pedals, so be it. I personally find climbing easier when I can spin my feet rather than only alternately pushing down, and I like being securely fastened to the bike at higher speeds or when the surface is bumpy. My preference, OK?
