Need to lengthen my carbon spinny pole by about 20 cm to bring it to the class limit of 4 m total. Been looking at adding a section to the aft or forward end, but can't seem to find a supplier with a section that will fit over or into the 38mm ID x 42.5mm OD of the pole.
Any suggestions?

I can get a completely new pole from Oz for ~$500 USD (including the $150 USD shipping). Would be more attractive if I could split the shipping costs with a double pole order...any takers?

Mike.
