P90X, Insanity, or a hybrid schedule of both workout programs?

[ShotoJuku]

My goals and objectives are to have a beach body by the time I hit college in August! I am in pretty good shape at the moment-5.10'' tall and a bigger guy but able to tackle even the most difficult exercises that slimmer guys cant lolz (i.e. my friends whom have hardcore abs). Although I am around 190 pounds, I have muscle in my arms, calves, thighs, and just want to get rid of the small chumb on my stomach (I am more muscle base than fat). Trying to find a nice diet plan as well? I'm considering on doing P90X first with my home bros then Insanity! Thanks for all the assistance everyone and motivation! To answer your question though... I am looking to tone up while at the same time build muscle and lose some weight.

Having done P90, P90-Master Series, and doing P90X, I would suggest P90X for one round at least with a focus on low fat, low carb diet plan.
