Lets assume that the correct shaft/lie/loft/swing-weight variables are fit perfectly to a player's Stroke. Pros and Cons of going with the blade versus a more "game improvement" type of iron?
It just seems that we discuss so much about precision alignments and the importance of sustaining compression that may be it would make sense at least from a training perspective to use a blade . . . if just for feeback.
Seems like the hands could be get a "masters degree" education with feedback from a blade. But I guess the flipside is this game is hard enough as it is.
