Well, some reason I am not surprised with the Speedblade irons. lol
Here is an excerpt from the Taylormade website for the Speedblades....
SpeedBlade irons take our Speed Pocket™ to the next level, giving golfers an instrument that will change the nature of their approach shots to help them hit more greens and shoot lower scores. SpeedBlade is radically differently than any other iron in terms of look, speed, launch, spin, feel, sound.
Visually, SpeedBlade irons are striking, combining a two-tone, satin nickel chrome plating with dark smoke satin ion plating (IP). Internally, the key performance feature that separates SpeedBlade from the pack is the Speed Pocket, a handle-bar shaped slot in the sole of the 3-7 irons that enables a large area of the face to flex and rebound at impact, resulting in faster ball speed, higher launch and better feel.
Just surprised no 3wd or Hybrid. Those have been advertised by Taylormade too, but I'm sure they too would just be a direct reflection of some other club here. Just change the picture and price, throw in some half hearted description and call it a day.
