**edit** I'm using 2 manfrotto Avenger F1000 suctions, 3 super clamps, and a magic arm. i've also got 12' of 1.250" aluminum tubing, with wall thickness of 0.058". When i tested it at the metal shop the flex wasn't that apparent, but now that im testing stuff before going live im getting a TON of pole flex. once i load the end of the pole with the magic arm, super clamp, d90 and wide angle, and amount of bounce in tube is unbearable. im not getting any sharp images, even when pushing gently on flat ground. Does anyone have any advice for how to stiffen this up? I realize i COULD go carbon fibre, but thats like $800 for tubing and im not dropping that yet. ive been reading all over the place and am looking for suggestions. Whatever the solution, i need it to be portable.
