Thanks for all the feedback!
@Gloersen, sorry for the lack of background:
The boat is 2014 Mastercraft prostar, the driver is the instructor so very experienced, I get very smooth and consistent pulls, the ski is like Radar’s butter knife, I think it’s an O’Brien. It’s both feet in, I’m LFF. I borrow it. I’m a 31 year old female, weight is about 58 kg, never done slalom before, just 2 skis. I have my own Radar lyrics with double boot binding and i was able to stand up and even ride a bit once, but not with an instructor. My instructor wants me to learn on a wider ski first so I haven’t been doing my ski at all. I also use a v-handle rope. Also, I’m able to get the ski to plane, but when the boat accelerates the ski starts to wobble and i fall.
