Re: rod rigging replacement
Landfall 38?.. nice cruiser. I can't see any reason not to go with wire, not sure about Dyneema or composite, cost and terminals might be the biggie with those.
The fact that rod can fail with little warning - esp old rod (don't ask...) and wire can usually let you know when it's getting close I'd think that esp for cruising wire would do just as well. Use mechanical fittings at deck level and you've got some DIY-ability too.. But I'd expect you'd be looking at somewhere around $3-4K for complete standing rigging even with wire???
