I've mentioned the DIN14 because it seems you would be able to fit in a DIN12 binding comfortably (which is light, but most FIS skis will come with higher ones)
Although the racing skis don't change a lot, I would say recently they've got a bit of tip rocker, higher radius and softer tip flex, which helps with the initiation. I think it makes them a little bit friendlier to ski (still, it's a race ski, so you have to work it)
Me personally I'm not much of a versatility ski person (I'm normally in GS skis) but I think the FIS SL are a bit too specialised tools, due to their weight. In some conditions they can be a drag. So I always question myself if I would spend the whole day in one of those SL ski (like the one we are discussing, or a Head Rebels iSL FIS, stiffest ski I've ever tried) . On the other hand, I would in a Hero ST TI, for example, so trading a bit of the top performance for a bit more versatility. But this is just a personal biased opinion.
Regarding the FIS GS they are quite manageable, if you care to ski them right (sometimes the long radius is a problem, but if you have enough mountain, go a bit faster, you hit the sweet spot), so I think it can definitely work for you. Trick is not to go too long (increases versatility, controls stiffness), especially because you are not on the heavy side (the weight is important when you are contextualising ski info, me as a heavier skier, so take this in consideration)
I have an old Head R25 and I keep hearing the new ones are even more fun (R30 womens and R35 for men).
I've used to ski several Atomic D2 GS (R18) and when I was comfy with it, I also had no issues with some of the FIS ones I've tried.
As for the Hero ST TI, nothing wrong with it in my book. It's right there with the top consumer SL skis, with the iSL, D2 SL, etc
