It's not necessarily the number of the club that's important it's more the loft of the club.
I'm content for the next month or two to stick with.
10.5° driver, 19° 3 hybrid, 4 6 7 8 irons, 50° wedge, sand wedge. These seem to allow me to get round our course ok.
Same boat for me as well; seniors have some interesting decisions to make 😳. I use the 6 degree gapping for my long clubs: D (11.5), 2i (18), and 5h (24). I left my irons as I found them, 7,8, and 9 (28.5 ,33, & 38). 2 wedges (50 & 58) and putter. 9 clubs.
