There are several stations around my area that sell gas with no ethanol but it is all 91 octane, In the sticky posts it says 87 is preferred for a pro xs, is it better to use the 87 ethanol or 91 with no ethanol?

Better to run the 87.
Oil, Battery, Spark Plugs, Fuel and Fuel Additive Recommendations
Top tier, recommended octane, ethanol fuel is all my Optimax has ever seen since new.Fuel Selection:
Make your fuel selections based on the following criteria, IN THE FOLLOWING ORDER:
-High Traffic, Top-Tier (Name Brand) Fuel
-Appropriate Octane Rating (see above info)
-Lowest possible ethanol content (NEVER to exceed 10%).
-While it may be preferable to utilize a fuel that contains lower (or no) ethanol, use of fuels that are SUBSTANTIALLY higher octane can result in decreased performance, decreased fuel economy, and potential for carbon buildup. Higher octane fuels burn SLOWER and COOLER.
