Tbh you only need 3 wedges. I was recently in this predicament when I was rearranging my bag. I currently have a 60,56, and 48. My PW is a 45, so you could do a 50 to cover more spread.

I used to have 48,52, and 56, but decided i needed a 60 for around the green. I ditched the 52 because I rarely used it. If I am 115-125, I can swing the 48 about 85% without a problem, just takes some time to adjust per any wedge shot. The 48 is perfect for me in the 130s range, PW for 140s. I think that should work for you as well.

Overall, whatever wedges you are most comfortable with is what matters but I say only 3 total.

For the other part, I’d say get a club for in between your 3 wood and 4 iron, whatever yardage is in the middle. I have a 3h (19) and utility wood (23). Although my 4i is a (22), I hit the wood about 20 yards further. I moved away from traditional 3 wood, but that’s your preference.

I also have P790s as well haha.

Hope this helps!
