112 vs. True Temper 112D

[Keta]

Maybe the magnet is picking up the spool shaft inside the arbor

I would think the same.

I don't know but wouldn't be too surprised if the arbor is steel.  The aluminum reduces weight and inertia.  But, arbor inertia would be about the same for steel or aluminum because it's at the center.

Prolly the shaft. When I first saw the fluting I thought "spool drainage?". The reel's a '56 so maybe mono-stretch damage was getting more common by then.
Noticed I don't see any True Temper versions with the counter-weight handle wrench, did they give that up, to cheapen the cost?
