I use vanilla Hammer gel; I find it not to be too sugary or sweet and the energy it provides to be pretty steady. I get too many sugar shakes from some of the honey gels, for example. I buy the big size and put it into a flask. I agree, though, by the end of a century I am pretty sick of almost all cycling supplements--ugh, and just wanting real food, and, uh, some Scotch.
The bicycle is the most civilized conveyance known to man. Other forms of transport grow daily more nightmarish. Only the bicycle remains pure in heart. ~Iris Murdoch, The Red and the Green
