re: Telling a begginer to “start from the hole and work back” is bad advice

I don't consider any single club "the most important" but to me there is a group of 3 or 4 clubs that are WAY more important than the rest - Driver, Gap/Sand Wedge, Lob Wedge, Putter.

I don't get a lot of practice only time at the range (usually my range time is before or after a round) but if I do, I'm only hitting driver and wedges. Getting better with those clubs drastically improves scores quicker.
