Same here, but I don't use the lightweight heads. Tried them, but found going with a normal weight head(200gr.+/_) & using a heavier shaft worked things out, along with a low loft(7.5). The best combo I had was a 193 head on an 81 shaft, but I was an FGIer back then, so you know why I don't have it any more.
46 1/2 is good to go for me. And I'm Typhoon's size, and a hell of a lot weaker! (a bit older too😉)
