They look great.
Still need better control on the temp
What issues are you having, overshooting? I always struggled with temp control for the really long cooks when you need to keep around 95/100 Celsius until I bought a temp regulator fan.
The problem with just using the vents is that even the slightest bit of wind has quite a big impact on temp swings so you're constantly having to tweak the vents to compensate and it always ended up being a lot of work and I still couldn't quite get it perfect.
Not starting the kamado with a chimney starter definitely helps as although it takes a bit longer to hit temp, overshoots are massively reduced but I really recommend getting a fan you'll be amazed at how much better it is. I know the eggs are insanely expensive so it's hard to stomach dropping a couple of hundred more when it should just work but it's definitely worth it. Plus you can do overnight cooks which is a real game changer.
