My question is I got fitted for the ts1 irons for the dynamic gold 105 shafts several months ago right before winter started and recently I went to the store here in Michigan and hit the new True Temper Elevate shafts Pro Edition with the VSS technology I love the way they feel  they are soft and solid in feel in your opinion what would be comprable to the dynamic gold 105 between the two Elevate shafts ? Second question is if a person got fitted for any iron a proper fitting how long should a set of irons last despite the current technology like I’m ordering my ts1 irons despite what you may be currently working on or your competitors for the future how long should that set of irons last far as more distance forgiveness ball flight High mpf rating etc before half to go and buy whatever is popular?
