Brion,
I don't have the data, but Beth or Evan Leonard may. I assume you know them (or of them) but I know they did some of the testing on the JSD with Steve Dashew. Ever since then both Estar and the Dashew's are using Dyneema drogue lines.
There is also this from Donald Jordan (quoted from someone else, quoting him). When discussing nylon vs polyester in 1996.
"The increased stretch will not reduce the load, in a breaking wave strike. In fact it will increase it a bit. The drogue must pick up the load quickly before the boat broaches and must turn the boat into the wave. The cones near the boat perform this function and THE LESS STRETCH THE BETTER [emphasis added]."
I should also mention I have a huge preference for dyneema as well, and keep having to keep myself from using where it may not be sutable.
