Twanking, a great deal of anecdotal evidence (and even some fairly scientific measurements) would suggest that the old ones are lighter. Those knurled metal control knobs look great, but are nearly 10 times heavier (if memory serves) than the plastic/rubber knobs on the pre-refined.
Bear in mind, we're talking a matter of ounces here, not pounds.
