mtb addict,
I went into one of the four shop around me today and picked up nine spokes to repair a rear wheel. I don't try to stock all of the sizes here at home. I find that the LBS is a source for me of the things I don't need extras of. I will admit I paid the up-charge for them to stock all the various sizes I don't want to have around. And that price is reasonable to me.
The tariffs will hurt a lot of folks, but that is the nature of international trade. The reason I'm not screaming and jumping up and down is that I don't have any China made bikes. Now when the tariffs hit my Italian and Japanese friends I will likely join your band wagon. Smiles, MH
