If you want to turn the intensity up, you have to fuel it with carbs. If you don't like sugar, then stay with something like waxy maize. Honestly, there isn't a lot of difference. I think that starches or glucose are probably better options that fructose or sucrose, but overall, when on the bike, you want fuel that your body can quickly mobilize.
If you're riding for less than 2 hours, try taking just water. It shouldn't be that big of a deal.
