The discussion was about improvements in plastic shuttles (mav 2000 remember ) which have been minimal the last 50 years..If we want to discuss improvements of goose feather shuttles today and trough history I think this is suitable to another thread.. I do not agree with your analogy. the syntetic strings can be strung harder and provide more power/control than natural gut strings can provide (if it was just a durability issue all pros would use natural gut and have 10 rackets per match ready strung).. A more valid comparison is if we made a 0.80 super durable string that last for years before it breaks, but have extremely bad performance/repulsion.. It could still be 2 our of 3 (more durable and more consistntly (bad), but worse performance, 2 out of 3).. The "consistency and durability" would NOT offset the lack of performance.. Durability is utterly useless if the perforamncce isn't acceptable.. which is a prereq imop before anything else.. I sincerely doubt there would be a significant shift to plastic if prices where dropped.. If economics where the "only" factor and people does not care about performance they buy plastics over feathers even without a price-drop. just like people buy graphite rackets instead of sttel rackets based on performance, not economics..
