A Stronger Clamping Solution?

[liamlumiere]

I currently attach my taking lens to the Moller 32/2x using a RedStan clamp and although I do like this for horizontal and tilting 45 degrees, what if I want to do and overhead shot? (which I do). 

I'm using a Rectilux also (so it's even heavier) and this came with a very strong clamp but the problem is, there's only one point of contact and it put a dent in the Moller! (see photo). The Moller originally came with an excellent looking clamp that screws onto the end of the scope but the other side seems less secure as its just a screw-in tightener. It has two holes at this side and wonder if this is for a wire to be attached for extra security?

Any of you guys use these scopes for overhead shots?

Cheers
