Ok guys, here is a link to another technique we practiced. You've all heard of the fishing pole:

This is a pic of me just before making the backcut. After getting all the blocks setup, here is what happend:
-face cut was made (horizontal to ground & perpendicular to grain)
-attached half hitch & running bowline
-attached loop runner for speed line (speed line was slack)
We had a group of Texas A&M students watching this. I made the backcut by hand.... the piece dropped into the block, then we tensioned up the speedline a bit and let it run. One thing we left out that would have helped is a pull line: the piece was almost too light to move down the speedline on its own.
Oh ya, just for fun - here is a pic of some of the guys.... holy cow, look at all those ropes
