Depends on how precise you want to be and what shafts you are using. In theory, if shafts are trimmed properly in the proper progression, the install is accurate with heads that progress by 7 grams throughout the set and have consistent bore depths, then you should get the proper flex progression in the set, if built to traditional length progressions. With todays tolerances of shafts, results overall are a little better than they use to be, maybe. Parallel vs taper tip sets, graphite vs steel, all can present different challenges. Building a precise frequency matched set can be a time consuming process, with adjustments generally needing to be made either in trimming or head weights, to dial in an exact progression. That being said, an exact progression is generally not something that is needed for a set to be consistent. If you can get a progression of 3 to 4 cycles between progressive length clubs in a set, that is good. I don’t think it is possible with any shaft to pull 8 shafts off the rack, build a set and expect there to be no “tweaking” needed in the build to get a precise frequency matched set. So to answer your question, you would most likely need a lot of shafts to sort to get a set of shafts that would require little or no adjustment to achieve a frequency matched set.

Britt, to follow up on your answer, would GW build a frequency matched set within 3-4 cpm upon request? Would there be an extra charge? Thanks.
