1. I currently have ts3 irons. Cut 1/4″ short, golf prize z align cord grip, regular.  Maltby graphite shaft. Love them but they feel too light. I swung a player’s ping g440, with their ping shaft. A bit heavier than my ts3 and liked the Xtra weight.

Question. How much lead tape should I add to my irons to get to d0? Given the iron description above you can likely determine my current s.w.  Again,love my ts3’s but a little more weight would suit my swing preference . Thank you
