good PWO mix?

[SVFootball]

im trying to make a good PWO shake on trueprotein...

what's everyone think about this setup:

waxy maize - 50%
hydrolyzed whey protein high grade - 35%
creatine monohydrate - 10%
BCAAs - 5%

the breakdown of this is:

Serving Size 30 grams
Servings Per Pound 15

Vitamin C 0mg

i was going to use 4 scoops per shake???
