Great question Mark.
I think if you addressed this same question to most on the Seniors tour, they might tell you that they missed playing the older ball ! They would tell you that they miss the shaping of shots ; draws and fades and generally the joy of "controlling" the ball in comparison to the modern balls !
For the average golfer, I doubt that playing the 1.62"" ball would make all that much difference. For them, it's mostly in the equipment - and hence my continuing argument for a roll back !
I must be getting bloody old, cause I remember all too well the old trusty 65's (my favoured selection) and as I've said on here before....they didn't scare me in my efforts as an extremely "average" golfer !
As for the effects of the 1.62" on the design of a course - this has already been tried at Loch Lomond (I think) with Paul Lawrie (I think) and he found the experience a breath of fresh air. He played both a modern and an old 1.62 for comparison and found the older ball more tricky to control....but more fun. If I remember correctly, there was a distinct loss of distance in the old ball played with Lawrie's modern clubs !
But "who cares" about design and architecture in golf ? We must keep going forward and shouldn't stop nor impede the booming "bubba's" of the modern game....should we ? Unless, of course, we all grasp the nettle and consider the FACT that golf, at the end of every day, is just a game / sport ?
Roll back the golf ball - but not the Hoover ; internet technology ; cancer treatments ; penis enlargement patches ; etc.,, etc...
