For about 5 years I played without a single wood in my bag. Im a decently long hitter, but totally inaccurate with a wood in my hand. I dropped the wood, picked up a driving iron and some hybrids and begun to really work on my long irons, approach, short game and especially skilled shots (under trees, long bunker shots, buried lies). I got my handicap down near single digits and decided to pick the woods back up. Now that I have become semi-consistant with a wood, and I still have the amazing iron/ short/ skilled game from having to work my ass off around every course for 5 years, im now looking at scratch hopefully by the end of next season.
I would highly recommend this, if you are going to be playing for a couple years of course. It really made me focus hard on my short game and approaches, which are where you really lose strokes anyway. When I walk up to the tee of a par 3, im not looking to par, im looking to birdie every single time. Before I put the woods back on par 4's, I would no so much focus on getting there in regulation, but making sure I had no more than 5 foot for par every par 4. Par 3's and par 5's were my attack holes, obviously on a par 5 without a wood I wouldnt have the distance to get there in 2, so that was some pressure and possible bad decisions eliminated from my game. I would focus on getting to the green in 3 (2 iron, middle iron, wedge) lagging one up tight and walking off with a par. With this approach, Pars came easy, bogeys happened... but so did birdies.
...and now that I have the big dawgs back in the bag, and I have a huge amount of confidence in the short game, it allows me to rear back and fire off every tee box, because even if I get in trouble, I just revert back to the old ways... play for par.
