I meant for cores. Polyester core and cover. Yes, I'm fully aware they make most cover from polyester and that sta-set is very common (I'm a New England
Ropes dealer). But that's b/c it's a good line built to a price
point. Performance wise, there are better choices. Blended covers, and Vectran, dyneema, etc. cores, but your average sailor thinks sta-set is expensive, so that rules out the better performing cordage.
To bridge the gap between the two NER and Samson
have come out with blended cores that are cheaper than the all out racer
lines. VPC and MLX respectively. Both of these lines are a great upgrade w/o breaking the bank.
