Hi Mark, Thanks for replay.
I checked both of my spool and the result has been the same. So, I understand now that SW version has a stronger drag compared with FA version (never played with 5000SW). I love my stella 5000 FA (it's now 5 years I fished whit) and I think, hope, it will service me for other years. But, at now, I will stay whit the class of rods mentioned before.
