I don't claim to be knowledgeable when it comes to woods mods. I'm in the just get a bigger saw camp.
But, I think Mastermind has some street cred. I know Treemonkey, Timberwolf, others have built some nice running saws. They may be dead for all I know.
But, you have to keep up with it as saws change . I don't know any good way to do it other than buy some top ends and test them.
I don't know a damn thing about modding a saw, but I bet I could start a you tube channel and convince some morons that I do.
