I was fortunate enough to get an exquisite brown gator strap from my RM dealer when I purchased my RM 10.
My RM is in RG so the deep dark croc strap complements the RG perfectly. Furthermore, it is one of the few straps I have ever seen that has croc on both sides of the strap - both inside and outside. As a result there is no staining from sweat and it is very comfortable.
I wonder why more strap mfgs don't put the croc on both sides.
Email me if you are interested and I will try to get you a pic. I believe the list price on the strap was close to $500 so it was not cheap !!
