Having now tried the tree major high-carb drink mixes, I figured I’d share my impressions and see if others will do the same.
Maurten 320 (80g serving): I didn’t like the taste, and this discouraged me from drinking it.
Beta Fuel (v 1.0): Taste was not bad, especially when cold. Noticeably sweet, and everything it touches gets kind of gummy and sticky.
Skratch SuperFuel (Lemon/lime): Taste was surprisingly OK; not sweet, and fairly tart. Thicker than regular drink mix, and initially it interfered with the vale on my bottles so it couldn’t suck air back in after drinking. This was cleared easily by shaking it.
