Good topic, Ian
I can hit my ball now with my equipment roughly as far as Tom Watson could with his ball and equipment in 1981. I base this on following him and Sandy tatum around Royal Dornoch in 1981 and my many plays of that course previously and since that encounter. What I could not then and still cannot do, however, is hit approach shots so cleanly and crisply as could and can a player of Tom's caliber (then and now). I am sure if we ever played together he would still outdrive me, and still play the aerial game to holes that I would have a hope in hell of hitting only using the ground game (e.g. the 14th at Dornoch).
But, getting to the question, this was also the case in 1981, when Tom and I were both in our early-mid-30s. Amateurs have ALWAYS had ways to attack great courses, if they turned on their brains from time to time and realised that they were never and would never be as good as Watson or any other of the 10,000+ top pros, and decided not to try to emulate them.
Interesting golf courses have and always will be "Amateur" oriented.
