I think I have all of the versions available and they are all working just fine ,operationally that is, ROI wise is another story. I was doing well at the start of DMR but steadily went down after a couple weeks. I think because, again, I can't stop switching methods. If I had the time I would run everything I have and see which version works best for me, but like everyone else, real jobs and real life get in the way. I guess that is the best advertisement for record keeping.
