Ubizmo, head on over to 1irongolf.com

They have all their clubs playing the same length and lie. David Lake has spent immeasurable hours perfecting the shaft tipping to get all clubs to play to the same flex - but the theory is that you have one swing for 10 clubs (Irons and Wedges). I think they've got a line of woods now, so with 1iron clubs, you'd have 2 swings (woods and irons).

There's a lot of people out there who love their 1Iron clubs.
