Mixing gels? Anyone do it?

Long chain, short chain, fruitcose, sucrose. Bla blah. Does anyone know if I mix gels will it come back to haunt me? I have kinda grown acustomed to mixing GU Plain with Cliff Shot Mocha in my flasks. No problems yet but have not tried it going real long. 5+ hours. I started to mix everything in training Accelerade, Gatorade and others to get my gut used to different things because races offer different items. Never a problem with the liquid mix but what about gels?

Great tastes that don’t go great together:

Vanilla Goo w/ KC MAsterpiece BBQ Sauce

Tangerine Power Gel w/Crest Tartar Control Toothpaste

Razzmatazz Cliff Shot with Cheezewhiz
