U see I don't think that is the case. I don't think graphite shafts were dominant in 1990 nevermind 1983. I'm pretty sure that in 1983 at least 98% of drivers had steel shafts and the remaining 2% were made up of prototype composites (graphite, carbon fibre) and maybe even hickory!
It seems to me that golfers switched to graphite on the PGA tour some time in the mid to late nineties but I cannot confirm this cos there's no information anywhere. I know that the senior tour were using them much earlier if this is what you mean?
If anybody could tell me when Ernie, Vijay, Phil or Davis-Love switched to graphite, that might be a start.
