At moderate swing speeds I find a big difference in height and trajectory between a 9 wood and a 3 or 4 hybrid.
I even own a set of "new" persimmons from 5 all the way down to 15 wood, which is equivalent to a 7 iron but with much higher trajectories .
I find it advantageous to have a 11 wood instead of a 5 iron or hybrid but it's so hard to find a good 11 or 9 wood in the market.
The Callaway divine 9 is ok but it's so draw biased I can't keep it in the bag.
I've been searching for a set of low profile 9 and 11 woods for a while... Anyone know of any?
