A bit more updates. Last two weekends I went to a same ski resort with carv sensors in the boots. The conditions were the same on both weekends - hard packed snow on most of the pistes.
The first weekend I rented Salomon X10 162cm which is more or less in the same category as the Head V8. A bit softer and more forgiving ski. On blue runs and easier reds they were nice to ski. In a way they basically do what you want when you want it. On slow speeds they turn as soon as you edge them a bit regardless of the forward/backward balance. I practiced bunch of javelin turns, focused on the stuff that app told me were missing (mostly fore/aft balance, and not rushing the turn initiation). I managed to get the Ski:IQ from 110 to 125 throughout the day, however the runs weren't consistent and would mostly oscilate around 120. All in all it was a great day and I definitely felt that I improved the form.
Next weekend comes and I wanted to give one more try to a stiffer slalom ski. I went to the same shop and rented Fischer WC SL 158cm (this was a FIS ski but with junior bindings if I got it correctly).
The difference in feel is substantial. I rode it on the same slopes as the previous ski's in the same conditions and the feel and security is simply better. And its hard to completely describe why.
Main thing I'd say is that it holds edges much better at the speed than the X10 (average speed on most runs is around 45 kmh with highest around 65 kmh). It also gives much more feedback while skiing, I can "feel" when is the proper time to exit turn and switch weight on the inside ski because you sort of feel the ski pushing you to do that.
I have no idea how much of that is really happening because of the ski or it's just in my head, but the result is that I feel safer to experiment and push myself with this ski. It really feels like it's cemented into the snow when you're turning.
I managed to get the Ski:IQ up to 134 and consistently have the score above 130. Forward backward balance improved a bit, but as soon as the slopes are high angled I tend to go into the back seat. In general I feel I skied better than ever and mostly decided that I'm gonna buy a ski from the slalom category.
Anyways, I went to return the skis to the shop where I talked with the boot fitter dude that I bought the boots from. Also in the shop was a ski instructor just getting his boots fitted. I was mostly looking at the Fischer SC 160cm. They're suggestion was still to go for the Fischer Curv DTX with main thing being that it's easier to ski when the conditions aren't ideal. But in case I wanna go for the pure slalom I should go for SC non pro version 165cm. And Pro version has a race plate on it which I assume makes it more stiff. I'm not sure about the height. I'm 6ft and 165lbs and from my understanding ski length should mostly be based on skill and weight?
Btw, here are the two examples from the metrics from the runs. The 130 one is on a pretty steep red run and 134 one is ona a bit gentler red run. If any more details in some categories can give more info let me know and I'll post them.
