These travel poles are a great alternative to carrying around heavy wooden poles. For the Stratus, order (2) center poles, either 8' or 9', and (4) side poles, either 7' or 8' . For the Cumulus, we only recommend (2) 9' poles and (4) 8' poles. That being said, the poles are adjustable so may be better to obtain the longer set.  Please follow this external link to purchase poles:
