Extensions = swingweight change

[B_R_A_D_Y]

I’m adding 1/2 inch to a set of graphite irons using universal extensions. What’s the approximate swingweight change? 3 maybe? He’s a +3 player, so I’m worried he’ll be able tell the difference. I haven’t seen the clubs yet so I don’t kno if there is a weight screw yet. Any tips?

General answer is every 5  grams you add to the butt end will decrease SW by 1 point.  Ballpark of 3 is probably a good guess. 
 

will he notice?  That depends on how sensitive the player is to weight; it’s  not related to handicap.
