azgreg My full bag goes D, 4w, 7w, 4h, 5i.
I've been playing a similar set up for some time. 16.5, 21 & 5H for years. My new irons (Srixons ZX5s) necessitated a new set up. I can actually hit a 24* 5i, so I am swapping out the 5H for a 4H now. So I will see if this set up works...TBD.
It all started with a MacG NVG2 7W. The sole profile always agreed with me. I have a steep angle of attack and a slower SS, so HL FWs always worked well for me.
The better question for me - would a 9W work in my bag? I picked up a 2016 TM M2 7HL 24* to find out. As @fatshot says Pinhawks may be something to consider. I have a set of these heads to build to find out as well.
