I'm all geared up to do some grinding to my Patron Pro's (which I absolutely love).
Fortunately I have several pairs of junk shells to practice on.
What I'm curious about is how thick the plastic is at the end of the toe and on the roof of it.
It feels much thicker than the cuff which comes in at around 4mm but it's hard to be sure.
Any ballpark guesstimates are appreciated.
