Hammer Gel's Apple Cinnamon rocks! I've been experimenting with different goos and found that I really like the Power Gel Green Apple and Strawberry Banana.. But step away from the Power Gel Tangerine. Its caffeinated, powdery artificial flavor is a horrible monstrosity of flavor design gone wrong.

Energy-wise, I am somehow happier at going up the hill with Hammer Gel, Power Gel, or Gu. If I don't have my goo somewhere at the base of the hill or midway up, I'm grumpy and unhappy and just not breathing right. Clifshots are okay, too.
