The bottom line to the whole discussion is that Lo GI and Hi GI don't complement each other. My suggestion is that you use 32GI with Redbar as your energy supplement for events. Both products are low GI(Redbar is arround 40 GI), therefore will give you a consistant energy level without spiking if used efficiently. Redbar will have their website up and runing soon and will have some articles that will answer the questions you are asking. If you want more info please e-mail me at chris@redbar.co.za
