A. You should have the best halyard you can afford - period. Smaller diameter the better.
B. Replacing the main sheave is easy and inexpensive so you should do it.

I think it is risky to buy an expensive halyard and then find out that YOUR sheave chafes. Just because other people have not had an issue does not mean you will not.
