Currently my Pearson 33-2 has wire/rope halyards. I would like to replace them with all rope halyards. Is there any reason I cannot or should not do this?

Welcome to the forum!:beer:
No reason you can't go to all rope halyards, but you need to make sure the new halyards are sized correctly for the sheeves.

There is a difference between sheaves for wire rip halyards and rope halyards.

Because the diameter of wire is different than rope, the sheave reflects that difference by two different widths ( an inner and an outer) of grooves. A rope sheave is only one width or groove.
You can try to modify the wire sheave to a single diameter groove. Or it is better to replace the wire sheave with a sheave designed for rope.

if you desire the properties of wire in a rope, look to using Dyneema rope rather than polyester rope. Dyneema will be near zero stretch. Polyester will stretch 12-15% At break. 3-5% at normal load.
