I think it depends how you define best but I think some of the best courses may be early casualtys. Best usually equals expensive, but not always, some of big financial headaches will be seen at the more expensive situations wher as the £10 munis dont have so far too fall, and they may actually get more business as more can afford $10 than $100. Well established members will probably be okay, key points will be location, supply of courses within a 30 minute travel period. Factors such as price and quality will dictate who gets lots of rounds and who gets not so many. We have a local 'not bad' course doing 4 balls at £32 per 4 (£8 each) every afternoon monday-friday. It must cost a lot more than £8 per round to service, yet I still see clubs pumping out deals that will eventually seal their own fates and continually hear from these clubs that their members no longer see a reason to join.
Course quality is a factor but only if factored to a price, I think the big problems will fall in the over £60/ $100 courses I think their target market will shrink quite a bit, some high profile UK clubs are getting less than 10 rounds per day.
