Are you looking for electrolyte but NOT carbs? If so, I've heard good things about the Elete stuff, too.

If you do want carbs, but hate the sweet stuff, I have two options. HydroBoom (from the makers of CarbBoom) is good but strong. It's not super sweet though, so I like it. I only use it on REALLY hot days...otherwise, it seems too strong for me and it can make me feel bloated. I haven't done a comparison, but my guess is that it's higher in electrolytes than the typical Powerade or Gatorade.

I recently tried PowerBar's endurance drink in the Sun Tea flavor. The day I tried it wasn't a hard ride or particularly hot, but the flavor sat well with me. It's not very sweet, it's light tasting, and it wasn't bad even after it had warmed up a bit. I ordered a canister and I'll try it on a hotter ride this weekend, but I think I'm going to like it. It might be worth a shot.
