I have been using Carb Boom gel packs for in-ride fueling for years now with what I feel is good results. I wouldn't even consider switching, but I have a racer friend who swears by Hammer Gel. Said he used to use Carb Boom, but is totally hooked on Hammer Gel now. This wouldn't be a big deal if I could just go to a local shop and pick up a Hammer Gel and try it, but no place locally carries it. Therefore, I'd have to order it online, so I thought I would see if you guys had an opinion on the comparison of the two before ordering any. Thanks!
