Up until LC+ came out, I ran only conventionally. Whenever I posted that I did, there was always at least one Legacy- or DCS-evangelist who felt compelled to jump in and tell me that I didn't know what I am missing. That was fine - its great when people are so passionate aobut their hobby. But actually I did know what I was missing: my first O-gauge set in fifty years (bought nine years ago now) was a Legacy SD70 set that came home with a full set of Legacy controllers and components, too. But within six months I was running conventional: what Legacy (or DCS) gave was not, to me, enough to justify what it cost (I'm not referred to monetary cost, but rather cost in effort, attention, time, and hassle). The Legacy system went in a closet, and I ran the SD70, some other Legacy locos, and some PS2 locos, in conventional mode, and was quite happy. Over time, as friend's systems had a this or that component fail, as seems to be inevitable with Legacy, I gave or loaned various pieces of my system to friends, etc. I have very little of it left now, although that does not matter: I have the SD70, which seems bulletproof, and run it, a lot, always in conventional.
Anyway, I was thinking about LC+, and conventional, and Legacy, and DCS, and all the discussion on this forum, and I made the table below to help me put my preferences in perspective. I rate nine characteristics of a power and control system as to importance to me, then give my rankings for each of the four types of systems I have considered. No available "control and power" system is perfect: in fact none even gets a score that would get you an "A" is schoo. The best is a high B. But based on what is important to me LC+ now slightly edges out conventional, mainly because at very little "cost" (hassle) it can run conventional, too. That is relfected in what is set up to run upstairs right now: five LC+ steamers (converted to "scale"), one DCS loco running in conventional (a PS3 BR-44 this morning) and two conventional locos running, uhh . . . well, in conventional, what else? (a pair of WBB 44 tonners).
I'm sharing this just to get discussion going and help this sub-forum get some activity: its rather dead on some days. I welcome any comments, any comments or questions at all, as well as comments from others about how they value the various charactistics I listed and evaluated as to how important they are to me.
