For me, a lot of it comes down to cost -- it can get pretty expensive if you have gel packs and powerbars every day. I mix it up, using powdered sports drink (Gatorade or Powerade), Milo

, Glucodin (very cheap at Coles), lollies, sometimes chips from a servo toward the end of a ride. I usually take 2 bottles, one mixed REALLY strong with Gatorade, and the other with plain water. I sip the strong one and dilute it as I go.
Well, 200km up farkin great whacking hills. Cost no barrier. Just whatever will get me to the end and isn't to much of a pita to carry. Milo? Dry or in milk? Wouldn't the milk gunk you up?
Yeah I was going to carry some zip lock bags of gatoraid to flavour the water I get along the way. The gatoraid/water bidons is a good idea. Get sick of gatoraid after a while.
