They were giving free samples of Hammer Gel Espresso flavor out at the MS150. The results were pretty impressive for me - it gave me a sustained burst of energy when I was beginning to feel the lead-legs coming on (of course it has caffeine too!). I had been using Honey Stingers, which weren't really doing much for me. The LBS guy said the Hammer is strictly complex carbs, so it doesn't give you the "easy come, easy go" burst that a simple carb like honey and some of the other gels would. Like we've said here before, it really comes down to what you can choke down while you ride! They all taste like nasty cough syrup! (I get a visual of Tom Hanks in "Big" trying to scrape that caviar off of his tongue at the party).
