Titleist ZM Forged Irons
These Titleist ZM Forged Irons are very similar to the Titleist ZB irons. The main and just about only difference is that these clubs maintain the same blade back throughout the entire set. The ZB's on the other hand are a progressive blend, similar to the Nike Pro Combos. Both are great sets of irons and very slick looking. You just need to decide if you want a more forgiving club in your higher irons or if you want the extreme blade stlye workability throughout.
