I like a fairway wood, and would happily carry 3/5/7/9 woods. I don't need a 7, as I carry a rescue (and don't own a 7, never have) but I do have a 9 wood in my bag at present.
A 9 wood Dave......what??
Yup, off yellows, it get's left in the dark and lonely place that is the cupboard. But off whites (the tees are far left), I'm using it on 3 holes off the tee to great effect....we have three holes where there are big trees encroaching over the left half of the fairways at about 140-160-ish from the tee. The big boys bosh it over with a high driver, the "hookers" bend it round with a 3i/rescue, I'm just sailing over the top with a 9 wood.....crazy.....
Hopeless off the fairway, give me a 4 or 5 iron any day.
I'd be nowhere without a 5 wood and would never swap it for an equivalent distance hybrid club.
I play nearly all the tight 310-330 yarders with it, leaving a 9/PW/GW in.......
