One thing people forget in overall club mix is clubhead speed. People with higher clubhead speed can hit 3Ws and 3 irons, because they generate the power to get the ball airborne with such clubs. Average golfers often have trouble with these clubs without special shafting.
For my current mix, see below In My Bag.
Long clubs. After 20 years of having some variation of 3W + 5W, I have gone with 4W + 7W; I'm now in season three. The couple extra degrees of loft make a big difference in getting the ball launched. And, the 7W actually outperforms hybrids in certain cases. As I have mentioned in other posts, Golf Digest reported recently on a study of fairway woods: The average golfer can hit a 4W more reliably - and sometimes farther - than a 3W.
Wedges. Another question is how many wedges? If you have a PW, and a same-model set of GW, SW and LW, you can develop a fairly reliable close-in yardage chart. This assumes you practice some to get to know your wedges.
I only carry three wedges, as I don't have a LW. But, I may change from 56* / to 54* + 58*.
The 4W + 7W has stretched the long end of my bag. I now carry a 4H also, and am debating whether to keep my 4i. In my new SLDR irons, the 4i delivers a strong, scary-accurate draw which is excellent for tee shots on short par 4s and long par 3s.
As for you, your bag mix seems OK. But, how are you hitting them? We don't know anything about your clubhead speed, accuracy, etc. If you think you will be playing more golf, you might get a fitting to see what you need. Also, a fitting might show tweaks you need for your current clubs (grip thickness, iron lie angle).
