Nanabush,
Fred Couples dosen't wear a glove..........
Tiger does, it up to you.
Most people are taught to wear a glove as it does have a valuble part of the golf swing in my opinion. Your left hand holds the club especially with the last three fingers, hence the leather glove to make good contact with the grip and hold on to it.
There has always been a teaching mith of holding the club lightly, this is correct to a degree, however you must hold on to the thing. People tend to squeeze the living daylights out of the club, that why it's always said "light grip" for me the wording should clearly be "relaxed but firm grip".
Golf Pride have some great grips on the market or if you like softer a feel try Lampkin, in the UK it cost about £30.00 for 10
irons.
Hope this helps
Ian.
