I am out of MP...can i use ultra size as long as the portion is adjusted to match the calories...I usually get 2 scoops of MP + strawberries...do you guys think it would be ok to use an appropriate exhange of ultra size with no fruit? Also, i was thinking of changing my carb-up day so I ate my carbs earlier in the day instead of waiting till meal 5. What do you all think?

That should be no problem for the exchange MP/Ultra Size. In regards to the carb-up meal, it's done as the last meal in order for your glycogen to be restored while you rest, you don't really wanna have it earlier in the day and then burn it right up again during activity. I'd keep it as my last meal like you have it in your plan.
