As light weight bars go, Stihl are the best and are worth the price. The performance and wear are same as a steel bar, but you just can't hang your saw out of Horizonal cut like a steel bar, they'll bend. On a long bar saw, it's total game changer for me, the saw is so much better balanced. I can't speak for the Tsumura, Sugi but when I was looking at these lightweight bars the Stihl seem to be the better bar. As my bar wear out, I'm slowly switching to lighter bars! I presently run 4 saws with Stihl light bars, MS362 25" .050 gauge, MS361 28" .063 gauge, MS460 32" .063 gauge and MS661 36" .063 gauge. My smaller saws I still run steel bars, but I don't seem to run those much anymore. There was lightweight bar shortage around here for a while and Tsumura and Sugi where available at the time but I choice to wait until I could get Stihl bar. I see guy running Stihl lightweight bars on Husqvarna more and more these days.
