I would definitely drop one of these and keep whichever one you find easier to hit straighter and higher.

I carry a 15 degree hybrid because I found it better out of rough than a 3 wood and they went basically the same distance. 

Good luck!

Agree with Hathan.  The hybrids are a much easier club to hit and more flexible.  I play them off the tee, off the deck and out of the rough with ease and confidence.  I carry a 14.25 913F and a 915h 17.25 in my bag and use the F for shorter par fours and the h for shots off the fairways because I can hit them both close to the same distance, but the h I hit with more accuracy.  You can figure the reasoning behind that.  My bag is setup for second shots into the green and I carry three hybrids and sometimes four depending on the course.  STROKESAVERS....... my longest iron is a 5 iron....
