Mike,
There was a recent post showing how someone used some small exit fairings, similiar to what is sometimes used where the rudder cables exit near the tail. I believe the plastic lines exit through a simple hole or grommet underneath those fairings. They can move & bend as necessary when the landing gear flexes. Clamping them further upstream, like Lowell did, seems to be a good idea to me. The lines need to exit the belly in front of the gear, and those little fairings would seem to give some protection & streamlining where they exit, and they could be inline with the fittings in the gear. Just a thought. I'm almost to that point also.
