How about the base bevel of your Elans and of your dads Fischers?
In my experience, the "above the ability" phenomenon is often (apart from the length, flex and maybe radius in racestock GS skis) caused by base bevel of .5 or even less.
(Your Elans should have 22,8 m which is not so much...)
D(C), we may be having the same ski. I also have an older Salomon GS, 190 cm, originally a womens GS. With the tip of only 96 mm or so it´s not so easy to get into gates but, fortunately enough, it´s fairly soft and bendable.
I can imagine that such or similar 194 cm stiffer version must be a fight to ski in some tighter courses.
OTOH, you got your fight and now you must find most new skis pretty easy to handle.
