POSH II pre stretched three strand spun polyester

[John Stone]

Anyone familiar with pre stretched POSH II three strand spun polyester line (Langman ropes) for use as halyards on traditional boats? I am told that it has less stretch than sta-set (in similar diameters) with good performance characteristics. Any suggestions for non color coded lines (seems harder to find these days) without the cost of dynema for use as halyards? It seems VPC would be a nice choice if it there was a plain white or buff colored option. Alas, it seems colors are in and vanilla is out.
