So do I need to override hash too? If so, are there any
recommendations as to how to determine the hash easily?
Sorry, just came across this thread that has some more tips:

If you need better performance from your hash function than my
previous suggestion, you can just pick a somewhat unique property and
return its -hash. This works because, while equal object have equal
hashes, equal hashes don't guarantee equality.
