Have you heard about or tried such combination? I'm afraid it may break because of stiffness difference.
The german Surf magazine has tested the Nautix NX-trem boom in August 2006 :

http://www.surf-magazin.de/test-cent...ln/gabelbaume/

Not a bad boom with regards to stiffness 5 years ago, as stiff as either a North Sail Silver aluminum boom or NeilPryde X3 aluminum boom which are labelled as "medium" stiffness by today's standard. However, this is an old-fashioned boom shape ("pinhead" style) and the front head is screwed to the body side tubing by 2 screws on each arm, which bond is prone to normal wear and tear of the holes/screws over time...

However, some new generation aluminum booms are 30% stiffer than that : Aeron OS Slalom boom, Prolimit Assault V-Grip boom & Severne Alu Race boom are the top 3 stiffest aluminum booms of the Surf magazine August 2011 test. All 3 are built with the new V-Grip-Form 32.5 mm diameter tubing that provides a much stronger stiffness under load than regular round or oval tubing.

Cheers !
