Most (If not all) gloves should have the same properties as latex on RP

[DioChasek]

A big part of me says that while it is a fun thing to pursue making glove forensics a bit more definitive to point out the crime, it also adds even more power to the security department which in the current meta is the last thing the community needs.

That being said, 20 is probably the most generous you should be, 7-8 characters is enough characters that, with very good rng mind you, you can pick out a matching set of prints or at least narrow it down to 2 or 3 options.
