I generally do 60-90% sucrose, and 10-40% Gatorade. Sucrose works as well as malto + fructose and is slightly lower osmolarity and slightly less sweet than a 50:50 malto:fruc mix.
Yes, I go pretty much 1.2:1 to 1:1 gluc:fruc all the time. Always via sucrose, which is glucose+fructose in one disaccharide, and Gatorade which is probably right around 2:1.
