Best trending endurance drink mix this spring?

Yeah, I got sick of basically making a car payment every month for my hydration and fueling.

Switched to flasks of straight maple syrup to replace gels and went with sugar/dextrose/sodium citrate and lemon/lime flavoring to replace my Skratch. The maple is still kind of pricey (but a small fraction of the cost of gels), but the drink mix is dirt cheap.
