Now you got me confused. I have had a new Slingshot Fuel 140 for a three weeks now with about 15 sessions in the water. I got the same sytem with Y original from teh slingsgot, except that I did not get the instructions on how to connect everything together.
I thought like this: the additional single lines (of about 7m) are just the extensions: you use them or not (for lighter wind, you obviously do). I used them in a way, that where the two center lines connect the single line I did NOT put the pulley (I just attached both lines to a single knot on a center line), but I put the pulley just between the single fron line extension and (above the) depower strap (I thought it is intended for the purpose of easing the tension when kite turns).
The kite worked pretty good for me in stronger conditions (15+knots), although I found it a little bit slow in turns and somehow depowered in 10+ knots conditions (yes I have lengthen the center lines for powering it more as much as possible).
One more thing: the kite has a big tendency (especially in lower winds, but it also happened in stronger 20 knots winds) to overfly me once in the zenith and usually fall out of the sky just a few meters away from me.
Is it because I did not use the pulley at the right place? (The manual that came with my slingshot is outdated and does not show anything about how to attach thh Y setup). What should I do with the overflying problem?
How it is supposed to be???? Anybody from Slingshot????
