Alternative material for rod rigging

[Coopjammin]

Hi Brian,
Firstly many thanks for producing the rigging handbook I never leave home without it and it's saved my bacon a fews times!

Following on from the thread, I specifically am looking to replace the rod on my 1997 Reichel Pugh 1D48 having done 3 transatlantic crossing in her I am now getting her ready for coding and ultimately day chartering. As such I will need a mast out rig survey and will need some form of work or replacement - under the coding regs this will need carrying out every 5 yrs. as I am on an Atlantic Island will limited rod facilities I am interested in learning more about other options such as dyneema - which presumably could be made up and shipped to me for fitting. What are your thoughts?

Regards

Ian
