It is a personal preference.  I was in the same boat as you.  I was a 4 handicap and then did not get a golf scholarship so I got away from the game for a while.  Now I try to play 2 times a month at minimum and I am back to an 8.

I use a 3 bag now because I do not have a lot of time to practice and it was easier to get used to those than having 4 in the bag.  I use the PW and I have a 53 and 58.  It has been working really well.  When I used to play a lot, I used the 4 wedges and it worked really well for me.

So, I added a 19 Hybrid to make a full bag.  I like it a lot. 

It can also depend on where you play and how long of a course it is.  If you are always playing a long course and you are not an exceptionally long hitter, then I would suggest the Hybrid.  It can go both was though, I play on a relatively short course and I hit long, but I still enjoy my hybrid for tee shots and shaping some shots.

This is just my 2 cents.  May be okay for you or not.

I have a bit of an unusual setup. 1-3-7 woods (2K7 Burner), 28.5 deg lofted fairway wood (persimmon 10 wood), 34 hybrid (persimmon),6-PW (Eye 2 green dot), 54-11 c-c, 60-07, 64-07 and putter (White Hot). There is 15 yards between clubs from the 3 wood to 10 wood and 6 iron. 10 yards between clubs from the 6-PW. The gap between full shots from PW-SW-LW is 20 yards. 10 yards between the LW and XW. No problem with gaps - I am pretty good at working clubs (you learn that when carrying a starter set for 7 years). I found out I fared better with a 7 wood vs a 3 or 4 hybrid in 2006 (when I took the game up after a 3 year hiatus) - I had played with 1-3-4, 2-PW and Dual Wedge basically since 1972 (used 3-5-7-9 irons between 1972-1979) and I even carried a traditional 1 iron in the 1980s. Ditto with using a lofted fairway wood vs a 5 or 6 hybrid. I hit the hybrids fine but get better distance with less work on the wood. I've carried a 9 wood or 11 wood since 2006. I've carried a 4 wedge setup since 2006. I discovered all the neat things one can do with a 64 degree wedge from 40 yards and less. I was using a 58 in 2006-2009 because it made the short game simple but the limitation was long bunkers and tight lies near the green. I also got into clubmaking in 2009 and constructed a set of irons (5-LW). Quite frankly, a gap wedge (except for the P2) has really not been of added value. One is that the Snake Eyes Q3 set didn't come with one and I learned how to work my PW and SW. My irons are "old school" (more lofted vs new and the PW is 50 deg) so no need for a GW.

I would look at putting a hybrid or two in play over the longer irons, but like others have said, that is a personal preference.  I will say that both the 909 and 910 hybrids are great.  And, you can find the 909s right now on sale at most golf shops.

I probably got off on a tangent when responding.... Since my other post about my setup (where I had 1-3-7 woods, 28 deg fww... Eye 2 Green Dot irons), I acquired a set of DCI 981 irons 4-GW (I use the 6-PW but can hit the 4-5 irons), had them fit and have been using them with good success the past two months. I still have the Eye 2s but am awaiting some shafts to complete a re-shaft project (I do a lot of my own club work, except lie and loft; I leave lie angle and loft to clubfitters). Then I'll re-evaluate vs the Titleists. The point I was making is sometimes one needs to get creative with his/her game to score well. Also, sometimes less is more. For instance, my minimum setup is 11 clubs (1-7 wood, 5H, 6-PW, 54-11 and 62-07) - I carry a 3 wood when the course I am playing has par 3s greater than 190 yd (the fairways are a bit tight on the courses I play and I am also capable of hitting the 7 wood 200 yds off the fairway). When I was using the Eye 2s, I carried the 34H in place of the 6 and 7 irons because of a distance anomaly (the 7 iron hit 3 yd less than the 8 and the 6 was only 5 yd more than the 8).
