A thicker cord (also twisted type) could've been used for the garrote yet it wasn't. So why choose expensive woven cord for a garrote unless it was something the perp used for other things?
Yes it's strong, but stronger than needed to make a garrote. What I read said it was a quarter inch wide and flattened.

What might that kind of cord be used for normally and what is the benifit of using that kind of cord rather than twisted cord?

Why that cord as opposed to twine? If the person was using a slip knot, it would be more effective.

This person knew exactly what he was doing - he chose his tools carefully.

This guy really knew what he was doing.

Unfortunately, its a bit like the Prosecutor's Nightmare when it comes to hate crimes: If a white man attacks a minority taken from a large crowd, the prosecutor can allege that it was a hate crime of some sort; whereas if a minority attacks one white person from a large crowd,,the allegation of 'hate crime' can be countered with 'selected a victim randomly' and chances favored the white person due to there having been fewer minorities.

So in cord selection, we are left with several alternatives:

Was it merely something lying around which turned out to be the best thing to use? Or was it simply picked by chance from among a wide variety of cords being sold? Or was it knowingly and carefully selected for its purpose?

The cord is sold at various Army/Navy Surplus stores and outdoor outfitter type stores. It is not some very rare item at all.

Rock climbing? Camping? Sailing? Equipment Stowage, such as in a Marina? Skydiving? Rescue work? Movie set construction? Displays and Exhibitions?(such as would also use duct tape).

The examples I've used before: a sniper shooting an abortionist and a total nutcase who is enraged by JonBenet having been permitted to step on a sidewalk crack, do not in any way require some sort of "personal" grudge. The anger arises more from political issues than personal interaction.

what I thought it was. Someone I used to know told me something once (when I didn't even ask - as I said before, I've been told things by others when I was just sitting and listening that perhaps they didn't even remember telling me later). Anyway, this guy told me he used to be a 'massagenest' (sp) (woman hater) but that he tried to get out of that by looking at little girls because "they were so pure" and all of that, and it occured to me that if this was him, that he could've seen JBR's image in the pagents as 'soiling' that 'pure' image of little girls.

I wrote to someone about my all of that long ago so this is just bringing some of it out into the open here.

IMO I can't see anyone as 'pure as the driven snow' but then I've lived longer than twenty years so that is why. Wont say how much longer, but longer.

It would appear the tape and cord and other things (rope, stun gun, Hi-Tec Boots)were carried into the house by the killer. That tells a lot about him - - and someone out in Boulder must have had some idea that this guy was involved - - his personality and things he owned... maybe things that went missing after the murder.
