1G Vacuum line -AN size choices

[all black 4G63]

just trying to research necessary vacuum line sizes when using -AN fittings.
I’m running two Tial waste gates and Tial BOV with JMF race intake, Omni MAP, FPR, brake booster, etc. I want to keep the aesthetics of the build so I want to go with -AN hose fittings and hose, but having sleepless nights thinking if -4 is too big or if -3 is better or if something else.
What are you guys running out there?
Thanks

Youre fine with a -4an thats a 1/4 inch line

Anyone know if AN fittings can be used with Tail wastegates? I want to run -4AN hose with fittings to the wastegates, but the Vibrant bango metric 10mm is too long. Anyone deal with this?
