Dear all, I came across the article/charts below at the weekend ( I know it is few years old). Apart from the length, how do the weights and swing-weights stand up to todays modern clubs. I am more concerned with the bottom chart STANDARD SWINGWEIGHTS CALCULATING THROUGH A SET rather than the SWINGWEIGHT FACTORS chart Are the any other charts for todays more modern clubs out there? Pre-Calculating Swingweight Swingweight Factors Swingweight Change Increase Factor By S.W. Factor Decrease Factor By S.W. Change +1 2 Grams Headweight 2 Grams -1 +3 1/2 inch Club Length 1/2 inch -3 -1 4 Grams Grip Weight 4 Grams +1 +1* 9 Grams Shaft Weight 9 Grams -1* The shaft swingweight equivalent is for illustration purposes only. Unlike the other three factors, as shaft weight changes its effect on swingweight changes at a disproportionate rate. For estimation purposes, however, the above shaft weight-to-swingweight equivalent is acceptable.

With proper trimming and installation, each shaft's weight will drop slightly through the set. Grip weight is basded onthe average weight of an M58 Golf Pride Men's Green Victory rubber grip. Although both the UDWS and UDIC shafts possess .600" butt diameters, most clubmakers purchase M58 (.580 core) grips. Therefore, the above chart reflects the installation of a .580 core grip. Traditionally the sand wedge and pitching wedge are designed to play at higher swingweights than the 1-9 irons. Shaft balance point is a parameter that is dependent upon specific shaft trimming. This shaft characteristic may have an impact on swingweight as well, particularly with a tip heavy or butt heavy design. This table appeared in Clubmaker's Digest, Vol 11, Number 4.
