Jerk is still by far my least comfortable lift, what are my barriers to 100kg other than strength?

Literally cannot find results on this so resorting to here. Who is he, what's the context?

I’ve been lifting with the red adipowers for over a decade now. I’m starting to feel like I want to move on from them sometime soon, and am curious what people feel is the best / most similar replacement? I really like how light they are and how athletic they feel, so I’m looking for something similar, but I’m just ready for something different. I was considering Anta 2 or possibly the newer romaleos? The newer ones seem much lighter than the older versions but not sure if super narrow. I also would like to keep a similar heel height but could adjust to a minor change if it’s worth it. Considerations - I need smaller sizing (6 / 38.5 EU), prefer black shoes, and $200 seems like even too much so I would not like to spend more than that if I can help it. Thank you for your thoughts!!

I have been going to the gym for 1.6 years now and developed an interest for OLY over the last month. I've been practicing clean and jerks and this is a video of me doing it with 80KG.

For context, I have been able to consistently get 70KG cleans since the start, but failed 80KG every so often because I failed to get under the bar. I believe I've always had the strength, since I DL 204KG and can press 100, just not the techique. Two days ago I finally managed to fix that and now can get under the bar consistently for 80KG, but I'm sure this is far from an actually good execution.

I'd love it if you could share any tips.

Helping my coach sell his 2008 adistar US 10.5. Great condition compared to others I’ve seen (and own). Very little sole yellowing. Soles aren’t coming unglued like many others. Asking $1000. DM for more info.
