Punch shot with 3wood will also go very far if u get a good roll. By 60% do u mean the so called "deep rough"? If it went 150 yd from the deep rough it would be impressive indeed. I cant remember being in 60% "normal" rough.
Yes u can hit from rough with 3 iron, with the punch shot. But as i said, u can use 3wood as well, which will go much further.
