So I have a customer who wants to create a outer loop to surround his 18 inch radius loop. I suggested a 22 inch radius loop, but I ran into a problem selecting which turnouts to get. I want to say that the standard remote turnouts (#44561) are appropriate but I don't want to be an inch off and have to order new turnouts for him.

So my question is: What are the best turnouts to link a 18 inch radius, inner, loop to a 22 inch radius, outer, loop?

Thanks for any assistance on the problem.
