Looking at 6.0 based on the LZ, EF, and hzrdus lines. I’m not a high swing speed guy and the transition isn’t super aggressive.
I have gone 80 with 6.0 and really liked the results on version 1.0 of the club. I have been fighting version 2.0, which was the same weight and flex, causing me to think it was hard stepped once. But I should have that answer this week.
