Hi,

The secret is to get drawn tube not extruded. ask for it. costs the same. difference is that it bends a lot before it breaks. they use this style of tube at AHPC. I have used it for years. Highly recommend for cross bars and spinnaker poles. My last spinnaker pole broke the wire holding the front pole just bent like spaghetti but never broke. Just bent back and used for the rest of the season.
