I've recenlty been looking at upgrading my VS2 to something a little better, and I have focused my search on DYE and Proto. However, I can't quite get it all straight. I looked at Proto's website and noticed that I can no longer find a PM8 or PM9, but only the PMR. My question for the smart people here are... what are the differences? Why is there no PM9? I heard that the only difference between a PM8 and a PM7 was the addition of a DM UL frame. Why onl a PMR now? What quality is a Proto SLG? A general discussion of the differences between marker types DYE and Proto would be welcome. Thanks.
