A 16 degree hybrid should not get you more distance then a 3 wood unless your 3 wood is an older model (most 3 woods have a longer shaft and are at the minnimum 15 degrees). A 16 degree hybrid (strong 3 iron or 2 iron) will have a shorter shaft and be more in line with your 5 wood distance. While the 19 Degree is a 3 iron distance.

The big question is how are you hitting your woods. It is not like you have any yardage gaps in your current set. Your hitting the ball decent distances and if you play more those should increase. If your comfortable with all of the clubs in the bag I doubt if I would make changes.

I would also hold off until you get a swing your comfortable with and then demo a few. Because you want to make sure you get a good flex of shaft for your swing and all of the heads on the hybrids are a little diferent. Wether off set or not, wether more like an iron or more like a wood.etc.
