REPLY:

Either metal-film or metal-oxide resistors are significantly more stable than
carbon comp. Their only possible disadvantage is that some values may exhibit
more inductance than carbon because the film is sometimes trimmed in a spiral,
creating a tiny inductor. It is very small but at UHF it may be significant.
Just something to keep in mind.
