Bills explanation a couple of posts ago is an excellent and simple
description of how it constant tension works and why it would be
beneficial.

Why don't we in Europe adopt this technology -- quite simply cost.
Without private finance of money/time/labour/parts few clubs if any can
afford to scrap their current winches and buy the new technology.

If constant tension was really necessary for a good winch launch, many
clubs would already have one.
But the standard system (Tost, Skylaunch, whatever) is good enough for
the majority aof the clubs here.

It's definitely nicve to have - but Bill would probably have an easier
job if he advertized a more simple and much cheaper winch design to
the US clubs...
