Which mooring balls at Cooper?

It's been several years since we bareboated, and we are finally returning in May. We chartered a 44' monohull. In the past I remember some rolly nights on monohulls at Cooper Island during the Summer months. Which moorings, if any, among the field are subject to the least amount of wave action wrapping around and affecting the anchorage?

Mid area to Southern balls close to the island. Generally most of the balls are fine.

Agreed, the balls closer to Quart-a-Nancy can be rolly on a mono.

Thanks! I thought so, too!
