The drivers have a kind of draw fade effect, but the iron shots are different, unless this was recently changed, as was pointed out to me. Then there was a lot of testing to confirm.
If the wind is right I like to 'draw or fade' my drives on PH 3, and a recent one* I tried on Oak. just for kicks. The results weren't exactly as planned but it's fun to try.
