Obviously I have the sheet metal too close
near the bottom of the rad.

Maybe, but don't bet on it.  Is the sheet metal actually touching the fins?

Towards the end yes. I know what happens if I go to the other extreme
with this rad angle.

With my first test rig (Dec 99) when I used the furnace blower a wall at the 
end of the duct would cause the air to stack up down there.

I am sure things change when the angle of the rad changes. Your angle
at 5 or 7 degrees is much shallower then mine which is about 30 degrees.

What have you found out so far? I wish you had a digital camera.
