Damn, sorry to hear about you BRS breaking. I thought the waist joint was fixed in later releases, not sure tho.
With the top 10 reissue poll coming along maybe wait to see if she is re-issued before risking another breakage.
Yeah, those hips will pop off if you try to be too extreme with the poses, but at least they are designed to pop rather than actually break.
Are there photos of the BRS break online?
