I've got 'normal' Stans in my tyres, and sealing hasn't been as great as I had hoped. For example, in my opinion (albeit subjective), the puncture in my front tyre should have sealed rather than required a worm. However, I have since bought some of the 'race' variety of Stans having heard that it is better for road tyres (although tried it out yet).
It sounds like you use a syringe to add the sealant? I'm guessing it's the Caffelatex one? If so, do you know if it would be compatible with Stan's race sealant? The reason I ask is that I ordered a Stan's syringe only to find that it wasn't compatible with their race sealant so I had to return it. So I'm looking for a different one.

I have mixed selaants before. Stans race sealant is a faff to add as you can't inject it. you can just about drain i into the tyre through the valves but it still clogs. Caffe latex is much better you can inject it. I use a cheap ebay syringe bought loads. little need for fancy inhjectors. Milkit valves though are nice but expensive at least with those you can draw up the sealant into the syringe to see how little you have left.

Just had to many punctures that would not seal with stans. Effoetto mariposa has been much better.
Hookless rims for MTB great, for road not sure. It would require alot of testing with all tubeless tyres before I offer it. I worry about tyre blow off at higher pressures. You have to account for the end user not reading any warnings. I am not sure what the advantage would be for road either as burping is not a problem unless the rim beak hook is hopeless.
Hippy there is a guide on my website (news section) which goes through how to live with tubeless tyres and avoid faff. read it. there is a badly shot short video of how you fix a puncture. sidewall cuts can be dealt with too. My own experience of schwalbe tubeless tyres has not been great they puncture too easily. they are comfy though and have low Crr so they are not hopeless.
