I use the ASW 28 cg hook for 2 reasons:

1. With over 1500 hours in the ASW 19 I am very familiar with aero tow
with CG hooks. (the CG hook on both gliders is just forward of the
main wheel inside the gear doors)

I also had 1000+ hours on my ASW 20 CG hook (and another 600 on other
gliders) when I had a forward hook installed.

2. The forward hook is a poor design which is difficult to hook up

True, but I noticed each line person knew how to do it the second time
they hooked me up, and no one complained.

and
poorly sealed.

Not that bad, but I did spend an hour one day sealing against air
instrusion (for winter flying) when I had the seat pan out for an annual.

Why go to any trouble at all? I found the forward hook (about 1 to 2
feet back from the nose) was better in a crosswind, better if the wing
runner was clumsy, better if I got distracted on tow, better in rough
air, and I never ran over the tow rope, which happened once in a while
with the CG hook.
