I use HEED and multi hour bottle of Perpeteum for all my long rides and races and I love the stuff. HEED is the best but I usually mix in a scoop of Enduralyte powder then usually bring another plain water filled bottle. Does a great job of washing down the Perpeteum. I really like the Lemon Lime and the orange is also good for a change up for the taste. I have a bottle of plain but haven't used it yet.
