Thanks; interesting comparison. I've used old AWs before and, except for the mysteries of properly adjusting the pull chain, they've worked well and have, if anything, too wide gaps between gears. I'm thinking now of the kickback 2 speed, with a second chain to accommodate the very large cog I'd require.
