I am thinking of upgrading to the v2 in the M80s. I am very happy with my M80s but I am nearing retirement so after that happens may not be able to do a lot upgrading. My question to those who have owned both is there that much of a difference noted? Also is the VP150v2 an improvement over the original VP150?
