I have the S flex on my KE4 Tour Hybrid and the shaft is just butter with gravy on top. I’m interested in installing the driver shaft in my Cobra LTD Black (murdered out). My current swing speed is 110 – 112 mph and I’m finding that I just get better control with XS shafts. Can the Pro Series DR be tipped to S+ or possibly even XS?
The MPF shafts have a 3.5″ parallel tip section, so you can trim from the tip to stiffen. Depending on the insertion depth of the shaft, you should be able to trim 1/2″ to possible 1″ and the shaft still should be OK. 1/2″ might get you 1/2 a flex and 1″ possibly a full flex stiffer.
