Question/help request,  I recently got a 58 degree SM8 with an "S" grind and have really found it easy to hit and has reduced my skulling/ and/or chunking.  
If I got a 54 degree SM8 for my sand wedge, does it really matter if I get another "S" grind?  It seems like they recommend changing grinds for a variety of conditions and lies but I'm not sure if matters so much at my skill level- versus having confidence in hitting which my new SM8 bring me.  Thoughts please?  
Does anyone else out there play the same grinds with their various wedge sets?  Thanks
