Brian,
It must be the type of wood you are cutting if you have to stop and sharpen the Oregon half way through a tank of gas. Granted, the Stihl is harder as shown by your experience, but I can cut clean wood for 3-4 hours using Oregon chain. If that means that I could cut for 6 hours using Stihl, it still isn`t worth the doubled price. BTW, I`m pretty sure that I know when my barbed wire is getting dull, LOL.
I`ve got some Laser chain from Jeff that does seem to be a really good product, harder than Oregon. I just sent a couple loops to Che to test, let`s see what she says.
I haven`t tried the Carlton chain in about 20 years because you can`t buy it around here, maybe soon though now that I have a source.
The Windsor/Oregon bastard chain sounds interesting but I can`t say that I have alot of chain stretch, so I may not see an advantage.
