Taipan Alpha vs Taipan Helix Alpha


Can anyone comment on obvisous differences between the older Taipan Alpha and newer Taipan Helix Alpha?
I am looking to upgrade the cord on a second Shunyata Hydra2 that I have, from Diamondback to Taipan. Just trying to make a decision if it's worth the extra money for the new series. I have a Taipan Alpha on a first Hydra2 already, so I basically know it's a very good cord. But how about the new Helix? Thanks...

is it as flexible as Audience powerChord? Because it will have to make a pretty good turn. thanks
While I am not familiar with Audience cables, the Shunyata Helix cables will make a 360 degree bend in about 14" diameter
