Samson XLS Extra T - What Splice?

[Bob Pingel]

There are several ropes in the world that are essentially dacron double braids, but mix in a little high mod to mitigate elasticity. In some cases the "core filler" is polypro versus dacron but that even "strengthens" my argument or question.

If you remove some dacron and add in some say spectra, do you automatically do a core-to-core? I know that a core-to-core in all dacron reduces the splice strength pretty dramatically.

Bottom line, dacron DB carries the load on both the core and cover, and a covered high mod carries the load largely on the core. If you start to mix in some filler material in the core, I assume that some material portion of the load moves back over to the cover.

So, just looking at a given rope and its component material, when do you switch from a double braid splice to a core-to-core?

Thanks,

Bob
