Three is the problem. Those are all very good relays

Why do you want to shorten it?
Every relay forces your follows to connect to another relay to get all of your content. The more you add the more duplicates you and your follows download. And the more you add, the more they need to connect to find all of your posts.
On the inbox side, if you keep relays that restrict who can post, like the wot ones, you will only get notifications from people they allow.
ok that makes sense. So you would you say that having more popular relays there rather than more restricted/private/paid ones is actually a better choice? I'm thinking damus, nostr.band, snort (for example).
No need to be large relays on inbox. They just need to be open for people to post otherwise you are not going to receive it. You can either pay for them to post or use a free relay.
