I hope to draw upon your collective experience and knowledge with a bit of a predicament.
My doll journey began about 1.5 years ago with a Tantaly Britney 2.0. Took some getting used to, but overall, I've been very satisfied with the doll. So much so, that I thought I'd climb deeper into this rabbit hole and upgrade, a task I've set upon last fall.
Now, however, having been through a full size doll, a larger torso and even a mini doll... I unfortunately had to realize something. For my use case, the Britney was just the perfect fit, and everything else ended up being a downgrade. Seems to me, other, larger dolls are more for the companionship experience, which I honestly don't really have an interest in, and for actual lovemaking, you maybe put them down in one pose or another, do the deed and you're done. For me, I like handling the doll more, trying multiple poses, which is not really something my noodle arms can manage with a 25-30 kilo doll.
I guess the thing is, the Britney's right on that sweet spot between being heavy/big enough to not just be a masturbator, but not being big enough to be a hassle to manage. However, despite her being seemingly the best option for me from everything I've tried, there's still a reason I set out shopping. Cause at the end of the day, she's quite a simple doll, practically just TPE on an unmoving metal "rod". But everything I've looked at either seems so much heavier, or just much smaller, skirting the line closer to masturbator...
I know the extra bits, like a head or half-legs are exactly the sort of things that would push it out of its weight category, but even just a movable back would be a huge upgrade imo, so she's not fixed in a permanent arch. Which I guess is something even some of Tantaly's own dolls have... but none of them have heads, which I'd also be rather partial to. Not only is oral nice, but I like dressing up and styling the dolls, and wigs, glasses and other accessories add a whole lot more variables to play with

(Also, I did check out Lovenestle/Erovenus' stuff, and even bought a Yuki, since it seemed to tick all checkboxes except the head, while also being rather cheap. It doesn't quite feel like what I'm looking for, though, the silicone holes are rather rough, and no head. Which some of their dolls do have, but they're once again in the 30 kg ballpark...)
So, TL;DR: Anyone have any knowledge of torso dolls similar in sizing/weight to the Tantaly Britney, but with more moving parts and optimally a head?
