I would highly recommend looking into Poseidon for increased performance all around. Personally my ideal in season stack would be as follows:
Xtend
Poseidon
Cordygen5
This stack IMO covers all the aspects you would look for in pregame preperation and it wouldn't be specific to only game time, but boost performance during practices, lifting sessions, and even school. Also I would personally the RPM is up to you as I don't know what the rules are in Florida (as far as I know NJ is still the only state to test in high school). Honestly though with the above stack I would save the RPM for off season training, or perhaps save it to in season lifting sessions.
Also with the Poseidon (if you are ordering online, which I hope you are for the sake of your wallet

) Nutraplanet is running an awesome deal that will enable you to purchase enough to cover you for a good duration of your season.
