I would step down the overlaps as you went yup - start with a longer overlap say 1 foot and decrease it by and inch or two with each downsizing...
The cumulative mechanical needs of the tubing are less as you go up - at the bottom all of the tubes are attached to the bottom one... the top piece does NOT have anything "after it"
