I've only tried Power Gel and Cliff Shots. Cliff Shots are WAY better! and the best flavour is sonic strawberry. it has added caffeine! yummy! they make a mocha mocha with caffeine, but I hate the taste of coffee I just saw that they have a flavour I want to try Cola Buzz, also with caffeine.

On our last road trip we picked up several of the gel flasks. my intention is to mix flavours up for an epic ride. maybe chocolate with strawberry, etc.

as for how well they work...well, I haven't gotten that huge burst of energy, but if taken at just the right time, I've avoided that huge dip in energy that a lack of fuel will cause.... so, yes, I think they work. DH just tried two at a time. He said he REALLY felt it then! heehee

Namaste,
~T~

back from a ride, too and haven't felt this good in ages!!
