I am 47 now, fat and not trained at all...and I have 3 drivers: LD version of SMT DeepBore, one of XXS Heavy Graffaloy Pro and my favourite Wishon Steel shaft - although they are for much higher speed swings. My SS is around 100 mph now, maybe 105 with graphite whippy crap. Never liked the feel of graphite; granted, my best drives were with graphite, but consistency is another tale.
Bought a persimmon driver and #4 wood recently on steel too - I shall see what it was in the 60-ies (the clubs are 1 year older than me...LOL). They will be a great addition to my McGregor blades from that era.
Graphite, steeper angles, bounce, dull leading edges, etc. make me puke...same as watching golf without punishment for bad shots.
Cheers
