all wheel pick up? insulfrog vs electrofrog?

[Coaltronn]

Hi,

I'm building a (DC) thomas the tank layout for my kids. I am looking to purchase peco turnouts. do you use electrofrog or insulfrog turnouts with your thomas locos? I was considering insulfrog as it will be easiser and cheaper but if needed will go the electrofrog route. its just frustrating to have to use switches and polarity accessories for that to work the right way.

thanks
