Where to place whirlpool return on a keggle???

[seedubxj]

Here is what I have. Looking for advice on where to place it on my keggle in relation to my drain and how high on the side. I normally do 5g batches but will be stepping up to 10g very soon if that makes a difference. But I would still like to utilize it during 5g batches as well. Thanks!!!

I have my whirlpool returns a few (3-5 inches) above the drain in both my 15 gallon and my 50 gallon systems

Bottom third of the smallest volume works to circulate the liquid from my testing.
