Well, a bit late now... but I should share anyway.
We just tested 2.0x.125 in our bender (another rotary draw machine, like your 105 except it's vertical and electric/hydraulic). It bent just fine, all the way past 90 degrees.
We have also bent 1.75x.125, 1.50x.125, 1.0x.125 square.
We ran all the tests on the tougher to bend (read- likes to crack) 6061 alloy in T6 temper. No heat, no sand.
Steel will be easy to finish and make it look nice, and most benders are best suited for that material.
