Congrats. I've been using a plain black Levy's M6 for a little over 5 years now. Levy's M6 + Schaller Strap Locks = Great. I dig the M6 because it distrubutes the weight nicely and well-it is more or less molded to my shoulder now.
The only reason why i would quit using the M6 is if i bought a Moody's.
take it easy.
