Another possible cause: Could it be that the halyard eye-splice binds in the block? A double-braid eye-splice leaves you with a "fat' area in the line, several inches long, above the eye; this can be thick enough to jam in the block, leaving you unable to haul the luff tight.
This happened to me on Bossa Nova, when I got my new C2000 mainsail last year. To see if that was the cause, I tied in a spare shackle with a tight bowline, above the eye-splice. Problem solved - it ran up tight and set right! I cut off the eye-splice and secured the halyard to the shackle with a double-bowline knot, the strongest knot I know for the job. It's been fine.
If you use a shackle, you can seize the free end of the bowline to the eye of the knot with a couple of stitches of sail-thread. Or you can be a real "old salt," and just tie the halyard directly to the headboard.
