Lou-As much as I am ashamed to admit it (especially since I am an OSU grad and a Columbus resident), I have not played it since the Nicklaus redo. Not that I haven't had the opportunity or access...maybe that's it, it's too convenient and there is so much golf elsewhere to see and play. Since I have not played the "new" Scarlet, I usually omit it from any discussion of Columbus area golf I am involved in. However, from what I have a gathered from somewhat knowledgeable players, the MacKenzie routing remains essentially intact but some of the MacKenzie/Maxwell design elements have been lost. The philosophy of the redo was to present the highest level modern player with a challenging golf course. As far as that goes, mission accomplished. Nicklaus deepened bunkers, located fairway bunkers in play for the ungodly length of the modern player and evened it out somewhat by softening some of the green contours. If it's a hard course you want, Jack gave it to you. However, what I loved about the Scarlet I knew was that it was demanding but ultimately fair and playable for most of the people who utilized the golf course. If you missed a shot, it was punished but recovery was possible with a solid shot. Now some of the bunkers are so deep that some of the members cannot get out of them (both literally and figuratively). Some people love the new Scarlet for it's difficulty and embracing the modern game. From what I have seen from Kenny Road and the area around the clubhouse, I am not sure I would prefer the new course to the old one. Some of the integrity of the original design may have been lost. But you must return to your Ohio roots and we can decide for ourselves.
Stoneycreek is indeed now Blacklick Woods, a very solid and affordable public golf course.
You are also correct that Champions (formerly Winding Hollow) was not an original Trent Jones project. He was brought in during the late 40's or early 50's to redo it. This was just before he did Firestone (which itself was a redo of a Bertie Way design). However, I have never heard Ross' name associated with the original Winding Hollow.
Lou, you are a fellow Buckeye and my favorite person from the Tiffin area but I don't see Columbus Country Club as being on the same level as Brookside, Worthington Hills and Riviera. Brookside has a good set of greens but has always seemed overly treed/claustrophobic to me. I can't remember a single hole at Worthington Hills. Riviera is solid but hardly memorable. The first hole at Columbus is much better than anything I remember on those golf courses. If you reconnect with your Buckeye roots in the near future, we can discuss this and the state of Buckeye football in greater detail. Hope all is well in Southern California.
