Hi John,
I've never had a line lay issue on Cetus - photos would sure be helpful.
Fluoro - YGK Ambercord 3.5lb.100 m spool (the diameter you can see is 8-lb Seaguar abrasion leader)
Finesse braid PE# 0.3, 150 m (don't remember if there's backing, but maybe a little)
Both have slight bias to the spool bottom that I would call perfection for a deep spool and locomotive drive
Again, it would help to see photos -- only photo I have are stacked surf-reel washers
- shallow spool, worm drive
tightening the drag also tends to move the line up the spool - I wouldn't over-tighten it, but see if loading with a natural working drag helps. - if you can, set the drag to 1/4 of the line test before you strip it.
