Has anyone noticed, or been troubled with, saddles that have two different sized hackle? Either it changes mid-stem, or more commonly one side of the stem is smaller than the other? The latter is OK provided you bent the stem for the long side and selected accordingly. The former just baffles me. I've selected saddles that were equal at the tips and base but sometimes as much a 2-sizes bigger in the middle.
I've seen it with regularity on both Whiting and Metz saddles and it really bugs me (pun intended)!
