PING G irons........love the way they frame the ball at address. All of the forgiveness is hidden from view. The impact on solid shots feels like you smashed the shit out of it. Sound is different as well as feel. The face of this model is a heat treated very thin steel. The sound and feel is kind of like a titanium face iron, like a K15 or Rapture. Flight is high like a shovel (think G15 or G20) and land soft. My longest iron is the 6, so I cannot comment on the 4 & 5. I chipped around the greens a lot today on the par 4s, using the 7 and 8 irons and these clubs really shine here too. Easy to pick it clean and run it up to the hole. These are strong lofted and I noticed. My PW is usually my 100yd carry club, but I hit twice today about 110. I hit the 6i about 150 - long for me. These sticks got me back to where I used to be on club selection. I guess the bottom line is, they play like SGI clubs, but look like GI clubs.
