All of it is going downhill.
Realtickling was the OG but seems to have been sold so RIP I guess.
Tickleabuse used to be great. Now it's a shell of its former self and can't even be considered to be the same studio. Pornstars aren't ticklish, stop trying to convince us otherwise!
Frenchtickling used to be amazing because of how candid it all seemed and how all the girls were girls next door types. Now he just follows the same system - 40% upperbody, 60% feet. end video. It sucks. Xavier had a goldmine and he butchered it. Every once in a while he has a great model (Shoutout to recent addition Yuming!) but for the most part I've completely lost interest.
I fucking ordered CUSTOMS for god's sake from RF Studio because I was just so annoyed with how crap everything was and knew the only hope I had of seeing a proper video was to have it done my way, but even they edited the video like shit and it turned out worse than it should have.
The only studio right now that isn't putting out straight trash is AmericanTickling but even he favors beauty over ticklishness every once in a while. It's not uncommon for him to have an absolute smokeshow strapped down to his table but who turns out to be as ticklish as a rock. Still though he's been the most consistent the past few years.
Czechtickling is also not bad.
UKTickling is mid but the girls are just caked in makeup and really overacting so it's offputting.
Zentickling is and always will be a solid 8/10. No complaints.
Gone are the days of Lolo, Brooke, Jackie French, and the other OG models who awakened me to this world, but I for one still go back to old TA and RT videos every once in a while because they were the best of the best.
I really have to disagree with what you say here about UK, or at least what you're saying is a huge generalization and only applies to a fraction of the models. He's had quite a diverse group of women models over the years, both when it comes to looks and when it comes to reactions to the tickling, a lot of them I'm attracted to, and a lot of them I'm not. I'm roughly guessing it's maybe something like 50/50 for me. I've been a subscription member to his site for the last few years, and I've gone through all of the dozens if not hundreds of the models multiples times, skipping over the ones I'm not attracted to, and I think his videos go back close to 15 years or so.
I will say I've noticed most recently that he's been doing a lot of repeats with models that go all the way back to the beginning, some of which I'm extremely attracted to in their earlier videos, but time is cruel to all of us when it comes to our looks. Many of the models I'm extremely attracted to go back years and years ago, and probably disappeared, either for that reason that they're getting older, or for whatever reason they don't do it anymore, or maybe just not publicly, and I know it makes me such a shallow asshole to say that, but in most cases, I think it's for the best. Of course, I ultimately think they should all do what they want to do if they enjoy it and we're free to watch what we like and just skip the rest. Some people really like seeing the older models and I see them requesting them all of the time, so to each their own. I saw on another thread on this site people insulting specific models, which is just crazy to me.
Since I've been a member, he has released some great videos with some really beautiful new models, Ellie Mae, Naomi, and Sammi P, to name a few of my recent favorites. But to suggest the models are just mid caked with makeup and overacting just doesn't apply to many of them, so I'm guessing you've maybe only actually seen a fraction of them and this is what you're basing it on. If you see models he had over the years like Louisa, Sophia W, Grace, and so many others he's worked with that way, that seems completely insane to me!
