on all rides : I always carry a little cash, just in case
under 40 mi. : I might have a banana along
over 40 mi. and under 65 : will also carry a small bar, like the Cliff Z-bar for kids (120 cal, just enough if I get lightheaded), and a gelpac just in case.
All Hammerfests 40+ : start with a banana and eat just before getting to start of hammerfest, carry and eat the Z-bar at some convenient point around , carry the gel just in case...
over 65 - 1 Z-bar, 1 full bar, and carry gelpac just in case

recently tried the stingers in both the Honey and the lemon flavors - I wasn;t excited, a bit heavy on sweet... clif bar/powerbar seems a better value, more my taste
