My 4 wood is a 917F2 16.5: Speeder Evolution 757 S, 42” / 78g; 2.7t. I love the club! What shaft would you recommend for me in the TS2 13.5 (STRONG)? My guess is a stiff shaft at circa 65-70g with 3.2-3.5t... Please give me some advice, preferably on a no-upcharge stick, thank you! But if necessary I pay extra for a shaft I like.
