I am currently using the M-Series+ wedges and before that Tricept, and CER.  Currently looking at the TSW wedges for the next phase of my journey. I have just noticed that the M-Series+ (and the Tricept) are 8-10grams heavier than the TSW.     This is covered in the M-Series description :

  • Slightly heavier head weights provide great feel for the shorter recommended playing lengths

The heavier head weights seem like a great idea, so why the lighter weights in the other models?  If I was going to hazard a guess it would seem that any wedges you make with the ‘slider’ design are heavier, the rest are not.
