Hi Clancol and
to the Forum.
I have 4 JYs and can recommend them. The so-called uterus-style vagina is very nice.
I have had that 170cm Shamus posted the link to on my short list for some time now (not necessarily that head though). I think weight wise she's actually closer to 40kg.
I have yet to see one advertised on Lucid's site with gel breasts, which is why I haven't bought one from them yet.
I have two XYs, a 170 and a 163. TPE bodies with silicone heads. The quality is excellent and both have gel breasts, although I have to say that you would be hard pushed to tell.
My own view regarding gel breasts is that they work better on the larger breasted dolls. My JY 166 has them and they are very nice. I find that with smaller-breasted dolls, gels can spoil the shape of the breast.
