I thought the same way when I started looking to upgrade to some lightweight bars. Then I saw the difference in price, and went with Tsumura. fordf150 had a really nice price on the Total Tsuper L&T bars. I bought mine from another AS member from Canada, and given the current exchange rate it was a steal; just had to wait a week and a half for it to arrive. The rails do seem tougher than the Stihl ES bars I had been milling with. They haven't seen as much use yet, but I've never had to dress the rails yet either. With the Stihls, I'd have to do them about every other time I flipped the bar.
