Matt,
I've never even considered anything but playing to the 150 marker on #18, even from the blue tees. A good three wood for me that lands in the left side of the fairway bounds along and leaves me with a 9-iron in. I've made two birdies in a row playing it that way so I'm not going to change it now!
For my game though, I hit three wood all day pretty much at BM (only hit driver on #5, 6, and 13, plus 9 from the tips to see how it played from back there). Helps me keep the ball on grass.
