Is it possible to trim discreet length iron shafts, e.g. Nippon N.S. Pro 950GH with a .370 tip diameter, to make the flex play between Regular and Stiff? With combo flex shafts I know to tip trim between the amounts shown in trimming instructions to accomplish this but I’m unsure if this can be done with discreet length shafts. Also, with the shaft I’ve referenced above, a 4 iron length shaft is 38″ raw, an 8 iron shaft is 36″ raw, yet the specs show both weigh 94 grams. I’m quite the novice at club building/tinkering, so I don’t see how 2 shafts separated by 2″ in raw length will weigh the same. I need all the help I can get.
