Personally use fruit such as bananas, pineapple etc (150g or so) in conjunction the 30-50g whey and and an organic egg. FOR ME, this works best as those particular fruits have a favorable glucose to fructose ratio (3/1 glucose) and a host of other vitamins and minerals that help in regards to recovery and general health.
Generally my next meal may be 1.5 to 4 hours later (I often train trice a day, so after my bigger AM shake at around 7.am I would have my next meal at 11.am- this shake will often have some m-casein in it as well and be higher protein, like 50g+)
I've never been a fan of Maltodextrin or pure glucose. Gives me the shits ;0)
Just my 2 cents, try an few protocols and see what works for you
