Here's a link for these creatures: http://www.mbl.edu/ARTICLES/Loligo/squid/
I think the arms can be short and tied to the shank at the eye, drifted or retrieved very slowly. With the eye at the other end, arms trailing, tied deceiver-style with long grizzly or white saddle feathers, the retrieve is either rapid jet-propelled escape mode or loose injured mode in the wash. The shape works well for long flies and the huge eyes may somehow provoke strikes too. I've had bodies come out well by tying tufts of Sea Fiber in succession, interspersed with krystal flash, then trimming back to the right shape. This results in a sparse, sparkly body which releases water easily for casting and looks great in the water worked fast or slow. I've been told by better tiers that my short-arm squid have "the proportions all wrong" and swimming backwards, but this link's video says they're OK.
