for the speed2 , select the Speed2 model with FDS.
as for the Pulse, they have not made the specs for the FDS but I wonder if you could just make the same as the Pulse1 or another model.
The FDS usually attaches to the same points as A1,B1,C1.
I dont think it really matter the length for the the 3 bridles, the most important is probably the total length of the FDS line
I bought 1 FDS kit already made by John for my SA2 15m, and he added a mixer ball to the main FDS line so the total length can be adjusted. When I got
it, it was too much long, so I reduced it about 3 feet by using the mixer ball. I dont think it really matter if there is a less than 1 foot
difference from the spec, the goal being just to secure on it.
The annoying thing is when the main FDS line is much too long, then you get tangles too easy.
