There are still three styles of screens to choose from for the 88 series, via CaseIH website. Coarse and fine mesh, and the vac system with the metal center.
The metal center is used with the vac system that sucks straw or chaff off of the screen. CaseIH recommends use with chopping corn headers, due to the corn sap (I haven't seen the sticky substance in MN, or SD. Some can enlighten me or others on that issue.)
For performance in other crops, I would say it is better or the same as the fine mesh screen repentant on conditions.
