I have mostly stopped using them and have not missed them. They are still on my heavy touring bike and will probably stay there, but I have been using a road bike for my road touring and a mountain bike if there is an off road component to the tour. Since I have been going very light, I am not sure if I will tour on the heavy touring bike again.

I didn't vote, but if you use them at home, I'd leave them on for touring. If you didn't use them at home I probably would skip them for touring as well.

BTW, when I used them I didn't find it that big of a hassle to remove them when packing for air travel or boxing the bike for shipping.
