I have used several different indoor launch monitors to establish my carry and total distance for each club in my bag.  My average carry for a 6 iron is 153 yds. which is SPF 2.  My driver clubhead speed is around 85mph (average 226 yds.), which is SPF 3.  So I should either be looking for an A shaft or an R shaft.  When determining my MPF which should I favor?  I strike the ball fairly consistently (center of clubface) so I’m confident with the readings I have.

BTW, I love your company!  Everything from product quality to customer service to information and education (like this forum) are excellent!  In this era of ‘no customer service’ yours is a pleasure to work with.  Thank you!
