Best Method for Syncing Audio

[DammitJanet]

I shot a film on 16mm and I had them transfer it to ProRes 422 for editing. Now that I've got the footage I'm ready to sync my audio and I'm wondering what the best method for syncing is. This is an important project so the more organized and stable the workflow the better. Any thoughts? Thanks!

I tried messing around with the Merge Clips (by in-points) feature but for some reason the merged clip it makes is always one frame ahead on the sound, so I had to set my in point one frame ahead of the slate clap spike in order to sync the clips. I feel like I shouldn't have to be doing that though. I'm told this isn't the most reliable function of FCP too. Anything I should know?

I went back and looked at my audio and found that the WAV files are running at 29fps while my footage is on a 23.98 timeline. Is this why it's not lining up correctly? Should i re-export my audio files at 23.98?
