YES! I love supercropping and use it exclusively to prevent my flowering plants from hitting the reflector glass. I go down 3,4,5+ nodes and bend the stem at a 90 degree right angle. You can "crush the herd" as I've heard it called where you squeeze the stem at the point you wish to bend, then rotate 180 degrees around the stem and crush again. This makes it easier for the stem to bend and not snap. Don't worry if you get a little snapping though...they will almost always recover.
LST is another good option, but not for that monster. Just bend over the taller colas and try to get an even canopy. After about 24 hours the tops re-orient themselves and begin growing up towards the light again. Sometimes the plant can attempt to correct the supercropping if you didn't do it enough, so you may have to give another gentle bend to the same spot to encourage the plant to stay horizontal a little more.
Good luck!
