I absolutely agree on not liking them for a primary though. For the conditions where they're good, nothing will beat them. But they're not great across a wide range of conditions.
Had a high tensile Danforth what had a slightly bent (unusable) shaft given to me.
Luckily we had a good hydraulic press at work.
My point was, yes they hold very well, so well they won't breakout well enough to keep from destroying them more than one would think.
