My preference is not to switch back it for implement simplicity, but I agree that it does not have a good compression effciency for a dynamic header not to be encoded in one byte intexed header rep. I think the current number of static header entries is enough too large compared to the frequencies to be referred. If we reduce a number of static header entries, it would be have a more chance for a dynamic header to be referred in the index less than 63.
