AR Vs Tortoise to power frog

Perry A Pollino

I posted a problem I was having with Locos stalling on turnouts, in particular a cross over.
After a lot of trouble shooting I discovered the AR does not always swicth the polarity when the switch moves. 
I am considering scrapping the AR's and using the Tortoise machines to swicth polarity.
Wondering if anyone has any advise as in does and Don'ts. I am N scale and using Barrett Hill Touch Toggles and thier tortoise adapters.
