I play a tight tree-lined 6400 yard par 71 course that I joined last July. Spraying my driver has cost me a bunch of strokes since missing the fairway generally means punching out with no shot at the green. Had the best back side since I joined (+2 37 at an 11 index) last week hitting my R11 3 wood with an 83 gram Blueboard off every tee after a terrible front 9 driving the ball, which kept me in play. I can feel the head during the swing with my 3 wood and feel like I can square it up since it's not a "balloon on a stick". Since then I purchased a used R9 420 cc head with whiteboard at 44.5", and after a few range sessions and adding some weight to the head (about 10 grams from stock setup), I'm really excited about taking it out. I am 5'10" and do not need a 46" driver by any means, and the newer heads seem lighter in addition to longer because of these crazy long shafts. I have a fast transition and can get quick, and for me, a smaller heavier head just feels a lot better, if I play a stock setup. I feel more confident swinging a shorter heavier headed driver, personally. Big fan of the ability to add weight to the R9 head, by the way.... a lot of the newer offerings are designed to play at 45.5-46", and if you want to play a shorter shaft, the swingweight gets all jacked up.
