its always a player preference. i you can hit a fairway wood well i say use the wood. if you have troubles try a hybrid. your suppose to hit a hybrid like an iron. 

In general, swing speeds under 90 will get better distance with a 19 degree (910F), driver swing speeds over 95 appreciate the utility/control with a 19 degree (910H).  The stock fairway is longer than a hybrid of the same degree, hence the distance gain with a slightly greater head speed on the longer shaft.

Specifically, try them both.  There are some that find one or the other awkward.  Personally, I couldn't hit a 15 degree FW (3W) or a 19 degree H (2H or 3H).  Have 24 H (4H)  and 21/17 F (equivalent to 4W/7W)  The 17 is dialed back to 17.75.  But that's what works for me.

Who told you that you shouldn't hit hybrids? And what was the reason they gave you?

910F 19* (set on the lower lofts - A2-D2 or A1-D1)  -  plays like a 7 wood on the A3-D3 or A3-D4 settings,  18.25 loft on C2,D2, C1,D1. 19* is a standard 5 wood loft.

910F 17* set to the A3-D3 or A4-D4 settings plays like a strong 5 wood.  18.5 loft on A3,B3,A4,B4

I have a 910F 19* and love it to death. 

910Fd has a larger head.

Best thing to do is hit the 19F and the 19H side by side.   Fairway wood vs hybrid is a personal preference.  Also, quite a few pros recommend a fairway setup of 4W-7W for those with slower swing speeds (I was eluded to this in 2007 by my dad).  The main thing is not to get caught up in the "hybrid hype" (how a hybrid is the greatest thing since sliced bread).   

Distance wise, I can hit a 21 fairway the same distance as a 17H.  If you check the specs, they just about have the same shaft length and lie angle.

I don't carry a 15 fairway because there isn't any added value - one is that I hit an 18 fairway just as far and two is that I carry a 13* draw driver that I hit very well.  Also, the distance gain between a 20 fairway and 18 fairway is about 5-7 yards max and the former is easier to hit off a wider variety of lies.

I have a 910F 19* set at B3 (with a shaft length of 41.5" - that is my longtime established length for a 5 wood) and I absolutely smack it.  I also can work this club and my 170 yard shot is a fully choked down stinger.

My "one-two" punch on the golf course has been the combination of 7W and 5H since 2006.
