You should use the largest core you can find, this will allow you easy
winding and better insulation. A large core will be able to handle
higher flux densities before becoming saturated, this is important.
I do not think you need to go to such a high inductance, as ringing in
the choke may become a problem in its own right. As for the material a
power core material such as Philips 3C85 would be a good choice.
