SpaghettiLens is likely to have problems with perfectly symmetric image configurations, but for this sort of system it should be fine.
I tried modelling it too with the two saddles from Model 1 by @JasonJason swapping position. Results similar: the synthetic image looks plausible, but the arrival-time contours look weird, which nearly always indicates the model is no good.
Another thing is the very wide separation of the points. Now, there are several lenses in CFHTLS with comparably wide separations -- but those are all groups or clusters of galaxies. A single galaxy producing such wide separations would be unlikely.
