Looks nice but where do I put all the stuff that now sits in the over-
spar storage area? *I don't think I want to discard my landout kit so
I can fit a vent system that has an unknown (to me) performance
advantage.

For me to be interested in a kit for the ASW-28 it would have to
extend the storage area aft so that, with the vent kit installed, at
least the same storage volume was still available, preferably more.
There is lots of room to extend backwards as is done in the 27's.
Unlike shorter pilots there in no room behind my seat and everything I
carry has to go just forward of, or over the spar.

Where can I find a picture of the installation looking aft into the
spar area?

An interesting gadget. *However, wouldn't it be more logical to vent
nearer the rear of the fuselage, say in the lower tail?

I have an exit vent in the lower aft area of the fuselage of both my
'27 and '28. With all the other stuff done sealing rudder hinge,
elevator drive, horn splitters, etc, it improved negative pressure and
flow and resulted in less noise. This vent is a huge ass ache to put
in with the associated nozzle, has significant structural implications
requiring reinforcement, and simply, is not for the faint hearted.
The new vent on top is in a low pressure area which helps a lot with
getting flow and reduced cockpit pressure. It also takes an hour and a
half to install instead of about 10 hr. It's structural implications
are minimal. It slightly reduces available baggage storage in the top
center 4 inches.
Both my gliders will have rear vents closed this winter and '28 will
get top vent.
FWIW
