Diameter of propane pipeing

[triple-oh-six]

I'm getting 2 of these:



I plan on hard pipeing them in, useing copper tubeing and brass fittings.
I want to use a bender so I can avoid excessive fittings, but the only one I can find locally will bend 1/2" OD tube.
(I'm also going to use the high to low pressure regulator from More Beer)

So what I'm asking is, what diameter tubeing should I use?
Will 3/8" ID (1/2" OD) be sufficient?

Prost,

Huh huh, I said "hard pipeing"

I used 1/2" from the input up to each 90 at the top, then from the 90 to the burner I used 3/8", I believe that is what the input side of the burner is if I remember correctly.

Nice setup, I love those kegs.

My main concern is restricting the gas flow with pipeing that's too thin.

I could probably find a bender online that'll do 1/2"ID, but I'm trying to avoid shipping charges.
