Fair enough Chuck and splices have their place and are quite favorable.
I'm a big fan but they also carry their own detriment.  Fattening and
stiffening the line and wasting 2 or 3 feet of line to freshen the nip to
name a few.

Any knot will reduce strength at roughly 40%.  A splice, done correctly,
will not.  In fact, rope strength is tested with a splice on each end.  And
it never breaks at the splice.

I've heard that a bowline can reduce strength by 50%.  Additionally a
bowline has a fixed diameter loop or eye.  It takes a good amount of
dressing the knot to make the eye small.  A bigger eye means that the knot
"two blocks" or jambs in the sheave sooner.  This could be a concern if you
are trying to maximize hoist for a long(ish) luff or if you're going
aloft.  I can barely reach my tri-color to replace bulbs or lens as it is.
A bowline doesn't present as compact profile either.  This could present a
problem with entanglement of other halyards at full hoist... Particularly
if that also includes a furler swivel.

A bowline works and does have the advantage of saving you from having to
cut the knot out.

Then again why use shackles and not just tie the halyards where they need
to go?  But what knot would you use - A bowline, at 50% reduced strength
obviously so that you could untie it.

Lots of options.  We didn't even delve into soft shackles.  I like the
Double overhand on itself knot for my purposes.

Nice knot.  If you’re going to go that route, why not just tie a bowline?

One thing to consider about sheave sizes which I did not think about when I
replaced my halyards... don't forget to allow for the eidth of your line
due to your eye splice for your halyard shackle. It obviously makes the
line much thicker and makes it harder to hoist the last 8"-12" or so of the
halyard without creating abrasion on the halyard.

It was suggested to me to instead use something called the Jeanneau Halyard
Knot... something I never heard of in all my years of sailing but it solved
the problem for me and now I can raise the the halyard 100% without concern
for halyard wearing out faster at the top... here is a link on how to tie
the knot for those interested and never heard of it like me... I am
probably one of the last people to hear about it... never too late to learn.
