What tank to get?

I have the two tippmann tipx's as some of you know, but I decided to use an HPA tank for both guns. I picked myself up a 4500 psi remote line that is split to go to 2 guns, so what size tank should I get for it? I don't want to carry my normal 88ci tank, that is too large for the type of play with pistols. So what size? I want a 4500psi carbon fiber tank, but what size would be recommended for this? I only shoot about 50-200 shots a day when playing with pistols so it doesn't matter too much about how much air it can hold, but I don't want a lot of weight. So to stop rambling, what should I get?

I have seen a lot of rigs for dual TiPXs that use a 13/3000 thank on the belt. That should give you all the air you need for the paint you can carry, you will have to reload the mags before you run out of air and then you can just refill all at once.

agreed check out Akimbo Assassins's video for his set up

Thanks guys, I will look up the 13/3000 and also look at akimbo assassins set-up (to be honest I forgot about him). :)
