Can the tow rope scratch the bottom of the ship?
Can the upward pull on the rope try to pull the nose
up?

I've used low-tow on several occasions in gliders iwth CG hooks. It's little
different than using a nose hook, as the normal sag in the rope generally keeps
it clear of the fuselage. I was once in low tow while passing through an area
of moderate turbulence, and ended up with enough slack in the rope to cause the
hook to back release. This can be a problem with CG hooks in low or high tow
position...
