I always thought some could make a difference. The Wishon Hi-Flight was magic around the greens although useless with a fuller swing. Of course it seemed to be just a Dynalite shaft that was untipped.
The old DG Spinner did seem to give me more spin on full shots and I rarely spin ball.....except when I land it just short of the hole and spin it back 10-15 ft 😡
I have heavy 125-130g Accra shafts in my wedges now. No different, but I love the heft and shock dampening.
