We keep ours tight. Replaced the monofilament after ten years due to UV
deterioration, not wear. We have a bikini and need to keep the boom off
of it.

My boat also came with the Garhauer solid vang and the Dutchman C system
("clothesline") with two mono-filament lines. One of the first changes I
made to the boat was replacing the springs in the vang with weaker ones
(from Garhauer) so that it wasn't so difficult to pull the boom down to
where it should be in light air. But that means that my vang is not
quite as rigid as yours.

Regarding the Dutchman, I now have the A system with 3 monofilament
lines and regret having made the change. With full battens, 2
monofilament lines are enough, in my view, and I never had problems with
the C system once I got it adjusted.

Furthermore, I am not comfortable leaving the topping lift tensioned
when I put the boat away, since with a properly adjusted system this
means that the monofilament lines are under tension and bearing a good
bit of the weight of the mainsail. If you read the Dutchman instructions
carefully you will note that with proper adjustment. Quoting from the A
system manual:  "Basically, the flaked sail hangs off the control
lines." I am concerned that this leads to premature failure of the
monofilament and (more importantly) to chafe between the main and the
monofilament when the sail is put away and covered. I'd rather have the
control lines relaxed and the sail tied securely to the boom. As a
consequence, I ease my topping lift whenever I put the boat away so that
the main rests on the boom and the monofilament is slack. As a
consequence, I don't really need the slits that were cut into my
mainsail cover, which seem to let in dirt, even though they are zippered.

To keep the boom from moving around (which is important--see below) I
support it using the main halyard secured to the end of the boom. You
have to secure it somewhere, so why not the end of the boom! The
monofilament control lines limit movement of the slack topping lift
enough that it doesn't chafe or get caught on other parts of the rigging.

Your idea of using a pennant to effectively shorten the topping lift so
that the control lines can be slack even while keeping a taught topping
lift is clever.  It occurs to me that you could get the same effect by
splicing a small hook directly into the topping lift a few feet up from
the boom and just hooking that to the end of the boom when you put the
boat away, leaving a small loop of slack topping lift. Or you could
switch to the C system which does essentially the same thing, albeit
with more complex hardware.

Note on keeping the boom stationary: Shortly after I purchased my boat
(used) there was a post on this list about a boat where the vang bracket
on the mast had failed. The cause was determined to be excessive wear
due to the combination of improper vang assembly and constant minor
motion of the boom as the boat rocked at mooring or in its slip. It's
important that the stainless part of the vang fitting not be allowed to
rub directly against the cast aluminum mast bracket! There should be a
stainless washer in between. Without the washer, the vang will wear a
groove into the center of the aluminum mast bracket just from minor
motion when the boat is not in use. If this groove becomes deep enough
the vang will "hang" in the groove when you ease the main away from
center line, creating enormous torque on the bracket at the groove.
Something has to give, and on the boat in question there was a failure
of the bracket. When I inspected my boat, I found the washer was not
installed properly, and that the groove was starting to form. I've had
no problems since putting the washer into the proper location between
the lower part of the vang and the bracket.
