Also, was the M21 only 2.20:1 in 1st? Kind of a bummer, I'm between a T-10 or rebuilding the Saginaw... I'll probably be a little over a third toward a new T-10 from Summit by the time I'm done with the Saginaw, but so far the Saginaw's been fine with me picking on it.
I'm still thinking I'll probably use the Saginaw, partially so I can get a feel how it all goes together... doesn't look too complicated from the videos I've watched so far.
