Why not Spectra ?

[Tom Roberts]

Hi,
As a new member I've learned a lot from browsing the site but mostly it makes me realise how little I know.
I'm re rigging a wharram 42 using his gaff rig wingsail. 34 foot alloy cylindrical spars with sleeved sails.
The spars have tangs so I won't be using drop overs but will use deadeyes and lanyards to the chainplates.
I've never worked with spectra but am prepared to practice 'til perfect. Will it do the job for my shrouds? I'm figuring on using ss for the forestay to avoid chafe from hank on sails.
Any advice welcomed and criticisms accepted .Thanks, Tom
