Perpetuem vs accelerade

Hello... I have been a big fan of Hammer products for a couple years. I have used Heed, Gel and many of there supplements. I was also using Perpetuem occaisionaly with success. Recently I started training for a 4 day ride from San Francisco to Los Angeles. My plan was to consume Perpetuem as my sole fuel source. As I began using perpetuem on my 100 mile training rides I started to have a few problems. 1st: I could not seam to get hydrated. after a few hours I would develop a very dry mouth and could not feel quinched. 2nd: the hydrating was worse at my original dose of 2.25 scoops an hour, but when I dropped down to 2 scoops an hour I felt under fueled late in my ride, and still felt dehydrated. I did feel that at 2.25-2.5 scoops an hour (recomended amount for my weight) that I was properly fueled, and I liked the convenience of one bottle for fuel and hydration...
I just bought a container of accelerade and would like to hear feedback from people who have used both. Can accelerade be used as perpetuem can for your "sole fuel source" for full day efforts? based on nutrition facts comparrisons they line up pretty close. Accelerade has a lot more protien and sugar. the carbs are fairly close....
