Thanks for the post. 

When it comes to matching the specs of you wedges to your irons, it is all player dependent. Some golfers like to have a little heavier shaft with more feel in their wedges, while others like a wedge to have a lighter shaft. The same can be said for the lie angle. Some golfers like to have wedges that have a more neutral (i.e. Std) lie angle.

The only way to know for sure is to see a local fitter and try some different wedges. I will say that the vast majority of individuals do not change the specs drastically from their irons. 

Hope this helps.
