Hey Scott,
Those mats are great, with my clumsy fingers if I didn't have mats under me my opal, mortality would be much higher. What I also cringe about and time seems to stand slow is when the polisher grabs that opal you've been babying all day and getting that final finish and "twang", there it goes flying at 900 miles an hour and you become a "jet fighter pilot" with the enemy plane flying over your cockpit and you wrench your neck trying to keep your eye on where it went,

I've found most of them and, surprisingly, almost all have survived the collisions.
