Buffness hit the nail on the head, as did the other response (forgot screen name). 50/50 is beneficial because you dextrose is a high glycemic simple sugar where malto is a high glycemic complex carb source. You get a nice insulin spike w/ both, but dextrose is in and out FAST where as malto takes a bit of time to get out. Fast/slow release. However, if like buffness you have a PWO shake then eat another meal w/in a half hour, all dextrose is acgtually better. Whatever fits yourschedule! Either way there won't be a major difference. I for one prefer white rice Post WO w/ some malto.
