I routinely hit drives at St Andrews in the 350 range and got my long drive of 380 there. However since moving back to the Legend tees on that course it seems that every time you have a heavy trailing wind your tee shot manages to hit into a mound or ridge, I rarely get over 330 there anymore. RSG has a number of places that seem to drive the ball forward even from the Legend tees.
I did watch a guy at BPB the other day on the par four dogleg left that you hit it over the trap, can't recall the number, hit one that hit into the heavy rough just past the trap and bolt forward to about 360 yards. He said he did it on purpose and that there was some hard area there, I'm not precise enough to hit it, but it did seem to work. Also for those playing #9 on BPB, you can drive it, even from the back tees left of the trap and carry it in the fairway to about 135 yards out. No wind or tail wind and you can find this area.
