On the Perfect I run 1.5 mm of down on launch and with the Perfection sounds like I need a lot less.
On both my C68s, the tow hook slot runs out at 115mm, and the securing nut is about 1/3 off the plate. To help keep the plate positioned flat in the fuse, I added a SS 4mm button head screw and washer just in front of the hook, at the aft end of the plate slot. The tow hook plate traps the nut, just as with the primary screw. Ideally, Samba should relocate the whole assembly about 5mm further aft than it is...can't imagine why anyone would run the hook at the forward-most position as it's located now.
And yes, over 1mm of down in launch mode sounds way too much.
