I'm a big fan or Dr Bob; the best golf advice I've ever read and not once does he mention "swing plane" or "spine angle".

The other thing to remember about his conservative strategy, cocky swing approach is that it's all very personal and may change from round to round. If you're hitting the driver great then use the driver, if you're having trouble with a pitching wedge then leave yourself an 8-iron to the green.

There are some excellent anecdotes in the book where the greats such as Nicklaus and Watson left a club in the bag all day because they weren't comfortable with it and formulated a strategy that means they'd never have to use it during the round (I seem to recall that it was the driver in Nicklaus's case and the wedge for Watson).

Another observation of Dr Bob is that the pros have the single-mindness to do this whereas amatuers will try to perservere with a club that's not working form them and lose many more shots in the process. As he says, practice is for the range, the course is for play (or something like that).
