I have (and use) Stanley #s 3, 4, 5 1/2, and 7.
Share your thoughts on cambers for the irons if you will.
The 3 has no camber now, 4 has a straight and slight cambered irons, 5 1/2 has a little larger camber, and 7 is open to suggestions.
I see and hear soooo many variations, and just trying to arrive at a consensus.
