try Carlton. I'm using Oregon, Stihl and Carlton and the Carlton chain is what I reach for first if they are all sharp.
Blount (the owner of Oregon) have recently bought out Carlton and already changed their bars (they used to be made by either GB or lately Tsumura in Japan but are now oregon rebaged ) but so far the chain is still the same.
Carlton is wholesaled by GB and Jakmax.
GB make excellent bars, and they are made here in Oz.
