ShopTalk: Driving Distances On Tour

[Graham Little]

Gentlemen   I'm preparing a seminar on golf hardware. One of the objectives is to give the audience a clear picture of the changes to golf hardware and what the real effect has been. I'm looking for some stats on average driving distances on tour over the years. Does anyone have a source for this data?   I recall the odd reference to this type of stat on this forum over the years but have not found an authoritative source.   Cheers Graham
