question concerning brewing 2 1/2 gallon batches!

[guinness310]

cheers and good day to all. I've been brewing 5 gallon all-grain batches for 6 months now and i wanted to try 2 1/2 gallon batches because i want to expiriment with more styles, spices, fruits etc.....my question was: do i simply devide my 5 gallon batches in half? Or is it more complicated than that? Will a 3 gallon cornelius keg suffice for storage? I have a 10 gallon coleman mash tun. Will that work just fine, given i strike and sparge with the appropriate ammount of water. im sorry for so many questions but im really getting into the idea of brewing these small batches, because i think it would definitely let me get extremely creative, without the fear of jepoardizing a full 5 gallons worth of beer.

I have tried 2.5 gallon batches in the past with some success. Cutting the ingredient quantities in half always worked well for me. However, based on a advice from a guy who owned his own homebrew supply store, I never cut the yeast in half...always pitched the full amount I would have used in a 5 gallon batch.
