Which brand mulcher head is best?

[rutwad]

I've looked around and guess what, every saleman swears his equipment brand is the best. This is where I need your help. Can anybody chime in about the FAE, Loftness, Gyro trak, magnum, or fecon mulchers?

Gyrotrac guarantees their Toma Ax 500HF will out cut any others. I looked at one brand (can't remember which one) that had chisel type teeth that needed sharpening. This seems terribly time consuming. Others have carbide-tip teeth with no sharpening.

What are any good or bad points about any? It will be used on an ASV RC100
