How to set drag properly with a digital scale?

[MichaelAngelo]

I did some experimenting today that I probably should have done a long time ago... experiment with a digital scale and my reels to learn what a proper drag setting feels like.

I experimented with two of my shimano reels... an old/crusty Sedona 4000 and a mint condition 3500B baitrunner.

I noticed some alarming differences between the pressure when the drag just starts to slip vs. the pressure during a quick pull.

Old Sedona:

1lb to start slipping and up to 3 lb during a quick pull.
3lb to start slipping and up to 7 lb during a quick pull.


New Baitrunner:

1lb to start slipping and up to 2.5 during a quick pull
5lb to start slipping and up to 7 lb during a quick pull.



So... how do I set the drag right on the Sedona when it can more than double itself during a quick run?

Does the 1/3 the line strength rule of thumb apply to a slow pull or a fast pull?

Or do I just need to fix the drag on the Sedona Razz Razz
