I have had one set of Rifle Lite 5.0 shafts "pured" by Golfsmith as
for factory shafts in Maruman forged cavity back irons. Theshafts came from
Golfsmith with the spline well marked. They included a report
on each shaft with the before and after graphs. I must admit that I didn't
fully understand every thing in the reports. But some shafts showed
significant variation from the factory position to the marked position.
I would not expect any factory to say they can't control their manufacturing
process or that "puring" would reap benefits. If they did, the other guys
claim theirs don't need it.
I am very satisfied with my finished product and the "pured" shafts perform
much better than my old ones...... your mileage may vary.
