What type specifically? And where?
From they types I have flown, I find that it's generally not worth the wear and tear on the structures, unless the taxi involves some serious waiting. Maybe the wear and tear on nosegear isn't as bad on some types, but we have found that the companies that do it as SOP spend a lot more on repairs and down time while saving some on fuel. They figure that it's worth it, most don't. I guess it all depends on the specifics of the operation.
