The top 100 should be courses you should be able to book and pay your fee and play. From memory Jezz said the latest GM top 100 only had 2, Loch Lomond and The Rennaisance and for me regardless of quality the shouldn't have been included
more that likely martin, the last time GM did its list i think Skibo asked not to be included ( i think they were top 30) at that time you could not play unless it was with a member and they just did not want visitors anyway. it was strange they started allowing the odd 4 ball but the cost is so over the top at £1200, im not sure why they bothered!
