I’ve read a lot regarding the FST shafts playing soft to flex. Between the regular 125 and Pro 125 does one play softer to flex than the other? Found an old chart that had the Pro at 306 cpm’s and the regular at 328 cpm’s. Yet more recent reviews and discussions suggest the Pro doesn’t play as soft to flex as the regular. Trying to figure out which of the FST 125’s plays closer to a true X-flex.
