Magic loop vs dpn

If the needle of choice is size (whatever) on 16 inch circular but instead you use magic loop. When they say to switch to the dpn’s to complete hat can you continue to use magic loop to the completion?

I don’t change to dpn. I finish the hat on the long circ I’ve been using. Working the other way, from the top, I use my circular for a pinhole cast on. If you prefer changing to dpn that’s a good way to do it but it’s not a necessity.

Thanks. Magic loop has saved me from constantly having to get new needles.
