72-micron rosin bags will offer higher yields compared to 36-micron rosin bags, but the 36-micron bags will provide the highest quality product.
You will get the highest yield from a 115-micron rosin bag compared with a 90-micron rosin bag, but the 90-micron bags will give you more filtration and slightly higher quality product.
36 micron - Most filtration available, highest quality output rosin for use with kief, dry sift, hash, and bubble hash
72 micron - High level of filtration, increased yields over 36 microns when pressing kief, dry sift, hash, and bubble hash
90 micron - a Higher level of filtration for use with flower, trim and shake rosin pressing
115 micron - Ideal level of filtration and high yielding for use with flower, trim and shake rosin pressing
