How to choose the right bobbins?

Plastic side, paper side, sideless or magnetic core?
It's a matter of personal preference.
The plastic side bobbin is clear to see how much thread the bobbin left. Paper side and sideless bobbins are more environmentally friendly. The magnetic core holds the bobbin securely in the metal bobbin case, maintaining continuous tension throughout the life of the bobbin.

Style L or A(Class 15)?
The L-style bobbin(20.3*8.9mm) is the most common style of bobbin used in home sewing machines. About the size of a US Nickel, it is also used in some longarm and commercial embroidery machines.
The A-style bobbin (20.3*11.7mm, also referred to as Class 15 bobbin) is similar in shape to the L style. It has the same diameter as an L-style but is wider, which allows it to hold more thread.

75D/2 or 70D/2
75D/2 and 70D/2 are both close to 60wt, and can be co-worked with 40wt (108D/2) top thread. 75D/2 thread is thicker, but our 70D/2 is made from high-tenacity polyester, tougher and longer,can be used at high speeds without any problems.
