Thank you all for the suggestions.
Having played some but not all I’d be inclined to go with something like as under. No real point imo, if your only seeing 10, in seeing courses that generically similar, especially if the same architect originated them. U.K. courses, not Irish.
TOC. Unmissable.
Somewhere that is still yee olde in style...say a Brancaster, Westward Ho!, Askernish
A Harry Colt heathland..could be Sunny New, could be Swinley, could be a lessor
A James Braid on unusual terrain...like a Welshpool, Perranporth, Pennard,
The most original Mackenzie course near Leeds
A hilltopper with grazing animals such as Kington, Southerndown, Yelverton
A modern ‘links’ where plenty of earth/sand was moved...like Kingsbarns or Castle Stuart
Carnoustie...a pretty old, evil/tough course on what is really a pretty flat piece of terrain
Somewhere bunkerless...say my beloved Minchinhampton Old (or Royal Ashdown Forest etc)
That’s 9 by my counting. As for number 10, well there’ll be something to learn from every other course mentioned above but some are a little too close in style to others so no point in seeing courses that are generally pretty similar when there’s a limit of 10. So, flip a coin time....with emphasis imo on a course by Herbert Fowler and/or Tom Simpson.
