I'll look thru posts to find out if someone else has tried assembling the poles from 5 shorter sections, instead of the three 17" sections.
Stock fiberglass rods and connectors are not expensive from kite-building shops.
The advantage would be sections just 10" instead of 17" long. The stock 17" is longer than the stuff-sack, and a drag. Small weight penalty from two more union connectors.
