Floatation for the T13

What should I use as floatation for my T13? I have a bunch of pool noodles in my Malibu Two. Should I just do the same thing for the T13?

Any thoughts on where to get some in bulk?
Thanks,
Andrew

2 liter soda bottles are light and have serious flotation

Hmmm never thought about 2 ltr bottles

my .02 cents about 2 liter bottles...they suck. when the temperature or air pressure changes, they make all sorts of weird popping sounds, it makes you think your hull is breaking. Secondly, the water level in the hull has to be deep enough to float the bottles and force them to push against the top before it will float anything, a few wedged in pool noodles will float as soon as the are wetted because they are already pushing against the top.
