I’m 33, 5’1” and about 120. We just traded in our 2017 super air Nautique for a 2020 GS20. I have been very active in all water sports since I was a kid but mostly slalom the last 5yrs or so. I’m looking for some tips. I am right handed big have always put my left foot forward. I don’t feel like I have a ton of control and it kills my back the way I’m standing. I lean back a lot bc I feel if I stand up then I’m wobbly, get drenched in the face and might go over the front of the ski. I usually ski about 21mph. Can you give me some tips about my stance, posture, feet, speed and the best ski to be using. Thank you!
