@Lazarus.Bird , pressing to vinyl doesn't mean your playing has to be technically perfect. Listen to the takes and see if they sound good to you even if the tempo swings. Sometimes a tempo change can enhance a song if it suits the mood of the song and players. Use your ears, if you find the tempo changes too much in a bad way then you just try again but be more aware of how fast/slow you're going. We've never used a click, yeah sometimes we'll listen to a song and say that's way too fast or too slow but we just try again it isn't that hard to adjust.
