Tom MacWood,
In all seriousness, your question is foolish, and cannot be addressed with a simple, universal response.
You would have me lump the infinite variety of play of virtually every high handicap player, "Duffer", into one monolithic "game", method of play, and strategic challenge. That is impossible.
"Duffers" have an infinite variety of golf games.
Some are long and wrong with every club, others are short and wrong, others drive well, hit irons poorly, others hit irons well, chip and putt poorly, and on and on and on and on.
The lower the handicap, the more the games of players and shot patterns merge. Whereas the games and shot patterns of "Duffers" are more divergent.
TEPaul,
Tom MacWood has a history of being an expert on golf courses he's never played, hence he's able to make these judgements, sight unseen.
You and I seem to think that NGLA offers an abundance of challenge, and quandries for every level of golfer, but what do we know, we've only played it a few hundred times.
