In my Pfaff h2L when I use the binder, the stich gets shorter than with out it....like 4mm.
Then I look on the Typical and says over 7mm or 6mm stitch lenght..so thats good
Also dont know whats the clone of the typical, maybe they copy a Juki model.
But Im most worry about the Typical 335vb if is good for heavy materials , and using also leather as a binding tape...for bags and sturdy works.
