That looks really interesting. I can see why they are a little cheaper because Eagle teeth has made a holder and then a tooth gets installed in the holder. Fecan has a large hammer with carbides on it. The whole thing has to be replaced. With the eagle system it looks like you could use carbides or shaving teeth with a quick change up but not have to replace the entire holder.
Not sure how those holders would hold up because I know our teeth get pretty smashed up. I hope someone on here uses them that can give a opinion on them.
