All the same on the bars here. I've felt unsatisfied for a little while, but hesitate on the Stihl bars since the tips are 2X the cost of the Oregon. I hoped the Oregon Pro was better but Madsen's has told me its the same bar, just prettier (true that!). I just ran a cannon today for my first day and it felt very good but yes its heavy heavy enough that I could tell the difference. And, as I had heard, it does run hot. But man its nice quality. I would totally try a Tsumura bar.
I would get about 2 1/2 months out of a bar (34" is what I run, I'm 6'3" it suits me well) and usually have to replace tips one time.
As far as chain, I think that I wiil say the Stihl is probably better but I haven't run any in a few years. As is typical with a number of my preferences, the half skip square grind is not available through my saw shop's distributor, even as a roll. I just got 15 loops of 75ck in the mail so I'll be running this Oregon more going forward. Happy to have moved on with the bar, feel ok with the chain though.
