I was mistaken. Did a search and discovered that Woodbine removed the Polytrack in 2016 and installed another synthetic surface called Tapeta. Surprised they did not go back to dirt like Keeneland and Del Mar did. If a horse has not run on it before usually look for good turf breeding or success on the sod to use as a resource.
I list them in my order of preference prior to the betting starting. I don't usually key any horse but rather like to look at the win, ex,and dd payouts and adjust my bets accordingly.
