TheTaylormade R11 Irons hit the shelves September 1st, 2011 and were engineered for the player who appreciates the shape and refinement of a tour-grade iron but needs the assistance of advanced technology to launch the ball higher, straighter and longer with less effort than their current clubs.
Wow. Thought about leaving my review as that, but I will expand. The R11s look a little rounded and a little oversized, but their performance is incredible. Ball flight is very long, without being too high, like a lot of game improvement irons. I was amazed just how straight the ball was flying as well, even on mishits. While I am not sure low handicappers will like the rounded, slightly-chunky, oversized look, I doubt they would deny the R11's performance. Ideal if you typically shoot in the 80s, and are looking to get into the 70s.

TaylorMade’s Precision Weight Port is a weight port permanently positioned in the back center of every iron head during assembly. This assures each R11 iron in the set is of uniform swingweight while also ensuring that the center of gravity location is precisely and optimally positioned in the center of the face between the toe and heel, also known as the “sweet spot.” The result is optimal consistency in feel and performance from one club to the next. The weights range from 2.5 to 17 grams and cannot be adjusted by end users.or tungsten and can not be adjusted by consumers
