These are yummy. I tried them at the Interbike Power Bar booth. What I liked about them was the little gush of liquid in the middle of the chew. Powerbar added that in there so the chew won't stick to your teeth, which is an annoying problem with the old chews. Genius.
You can get the Gel Blasts in four flavors: cola, strawberry banana, raspberry and lemon. The cola and strawberry banana flavors have caffeine. I preferred the raspberry myself as a great alternative to a Gu or gel.
