origin live silver or???

I currently am using a ol rb250 and have been for about 4+years. I'm still pleased and I would still like to move forward so do I choose the ol silver or what?????encounter?? TWL, I remember a thread re: your ab of the silver and another origin arm and I can't seem to find it in the archives. Perhaps you could give me an overview of your findings if you please. I am currently using a transfiguration spirit and will stay with that until I move on to a shelter. Thanks
