Try the Sugihara's..they are light and relatively inexpensive. Typically they can be had from their distributor of ebay. I believe Total bars sold by Tilton/Jonsered are built by these Tsumura folks, wonder if Tilton can get the lightened versions.
I've had a bunch of the Sugihara's now. They are lighter and they wear very well.
I like the tsumuras but finding them isn't easy to do in most areas. I could get 24" total branded tsumuras for $55 from a jonsered dealer last year. Its just a 2 hour drive to get them. I would like to be able to get stihl mount tsumuras.
BTW, All Sugi's come Sthil mount and you need those Bailey's Stihl to Husqvarna adapters if your like me...or modify/grind/drill nuts to be adapters..I've done that too. AND they track in the 50-60 dollar range
Last time I talked to Dave, he said he only carried what he considered popular sizes for his market (summary of what he said). I seem to recall him saying something about having to order 100 of one bar which is why he did not carry the smaller bars. We should do a group buy.
I tried to get some Sugi bars here in Canada but they wanted 95.00 a bar plus shipping plus tax and could only get the 16" bar I wanted in .325x.058.
Would the 16" and 18" Tsumura Lites and Sugis in the mentioned lengths be lighter than the Oregon Laminated in 16" 3/8 x .050?
