I used sampos my first year and had 2 fail and I couldn't get them to free up with boiling water or anything else. I recently acquired a few pineo swivels and I am never going back to sampos. 17 grams vs. 4 grams for the large pineo and no bearing to foul. They are expensive but two different people I know have 10+ year old pineos and they are showing no wear.

I do love the coast lock for field use though.
