Thanks for the input. I'll have to try a course a few times just to get the timing down, but in terms of raw learning and muscle memory a 6 ball course would be difficult to learn on. I miss a turn and I miss the rest easily. Bam $10 down the drain.
I haven't ridden many "good" skis, (or at least ones that looked good.) The rental I used most often said "7000" on the bottom and something else. I thought it was great the first time I tried it compared to another one that was a little small, I also blame myself for being so wobbly and inconsistent and not having the balance (my torso does not like relax or twist and I have a funny way of initiating an offside turn). The good skis I used early on I didnt notice too much of a difference, but when I went back to them a month later I noticed they were better right away. The D3 that was fast was ridden twice, the first time I didnt notice much of a difference, the second time was insane and I face planted into the first wake, party because the driver throttled it and partly because my form was shit. I remember one time when the 7000 was missing and I used a different ski. I did well on it making some of the most effortless turns I've ever done and stuck with it for a few days, then it just didnt feel right and I went back to the 7000.
The Elite particularly sticks out. When I went to the ski club in Jecheon for the first time the owner told me to use his ski because he was impressed with me. I really didn't know what I was looking at. After a couple turns it was clear that the thinness, light weight and glossy bottom made it incredible. The guy said he counted me doing 50 turns in the kilometer I did. The turns felt much easier and I got so much lower crossing the wakes. I even had a couple "holy shit" moments because it got my from side to side so fast. Maybe my memory is getting the best of me because I was having a "career day." As you can see I have my heart set on that Elite. I'd like to change my mind to an A2 or something deemed more stable but its hard to justify hundreds of dollars on something I havent tried out and cant try out, Im sure I'd be happy with it but I want to be 100% sure on a purchase. There are skis for sale but for a premium cost (The elite here is close to $2600) and Im sure there's a used market but I cant shuffle through all the Korean text to find it.
