BY your argument Macca we should ban all blocks, pulleys, sheet lines and fittings that have been made after 1975 because they are all lighter, more efficient, COST more, and are predominately made from "exotic" materials, and anyone who can afford to use them will gain an advantage by spending more money?
Does this sound in any way similar to your argument?
Sometimes today’s exotic materials (which become tomorrows standards) create resistance from "traditionalists" simply through their stagnation in the past, it was only a relatively short time ago that your same views were argued vehemently between sailers who wanted to convert their classes from wood to fibreglass and those who said it would kill their classes and sailing as a whole. History tells us who was right and who was wrong with that one.
