Don't know anything regarding his renovation work but he did The Harvester in Iowa and that course was awesome. I played it this summer on an extensive trip out west and liked it better than courses like Wild Horse, Redlands Mesa, Lokota Canyon, Circling Raven, Quarry at Giants Ridge, Hawktree, Old Works, Links of North Dakota.
So if his renovation work is anything like is original work I'm sure its good.
