Brush Cutter Blade Experiences???

[marks]

I've just purchased the Echo SMU 400 brush cutter, to clear woody material on the steeper slopes. It came with the 10" 80 tooth blade, and in consideration of future blade replacements the Beaver Blade has come into sight. Does anyone have any experience with this type of clearing, or other types of blades?

I have used a Beaver Blade on a DR trimmer and it worked well. I don't know how it would work on something like a hand held trimmer.
