I run Total bars, they are made by Tsumara. The Carlton Premium sprocket tip bars on clearance are the same bars with a differant logo. I haven't ran one longer than 24", but a 24" oregon is probably 1/2 to one pound lighter than the Tsumara. The weight might be an issue on a long bar. I found them because those are the bars that the local loggers run and seem to last. There is a pic in the shotgun muffler mod thread of the first total bar I bought. It had about 30 face cord on it in that pic and still looked new.. Who knows how much more I have on it, but I have only dressed it minimal times. I'll probably never buy another oregon bar again. If you run across a total bar that is painted....That is an old version made by BG.
I don't have much else to add, I have never ran the arborist pro bars or the Woodsman pro.
