I know most companies producing graphite shafts, feel that they have improved graphite shafts to the point that they do not need Purring. I agree graphite has come a long way. I personally feel, it is worth the $25 per club SST Pure, with GolfWorks.
How do you feel about Purring Metal, such as True Temper AMT metal shafts?
