I used to run a golf league and one week a year we'd have "Specialty Night" Golfers were allowed 2 clubs and a putter. Many grumbled and moaned about how that's not really golf, but many were surprised that they shot no worse or even better without their whole bag.
You guys talking about a 1 iron.....have you checked the specs on clubs lateley? Present day clubs with longer shafts and stronger loft make today's 3 iron almost the same as the 1 irons.
After Lee Trevino had his near miss with lightning at the Western Open years ago, he was seen walking down the fairway holding a 1 iron in the air. His explanation was "not even God can't hit a 1 iron."
