Well, I do think quite a few "raw" perhaps some "unity" lifters still use it in some form or fashion. Maybe there is a bit of miscommunications on our descriptions of linear.
Coan used it and it worked pretty good for him. Albeit before the super gear I suppose.
This was also an interesting read, vvv but mentions how Lou moved away from it more with the geared stuff, so I can see your points too.
