What would be the weight differences of a 5 iron to a 6 iron to a 7 iron so so forth all the way to the gap wedge ? Should the difference be say 7 to 10 grams between heads ? Took apart a set of SLDR ‘S and found some weights glued into the hossel below the shaft . After taking some measurements of the weights in the irons I found the differences in weight were . Weight increasing from long to wedges . 5 to 6 was 14 grams , 6 to 7 was 5 grams , 7 to 8 was 6 grams , 8 to 9 was 6 grams , 9 to P was 8 grams and P to A was 3 grams . Any thoughts ?
