ok the reason your shoulders are off, is probably that you modeled your shirt based on Hiro in his default position, not zeroed. you need to always turn off IK and Zero your base figure before saving the figure out to be used as a modeling dummy. cr2 editor is basically a text editor designed specifically for editing Poser files, it compresses things down to a more manageable level. so you don't have to wade through thousands of lines of deltas to find things. one of the nice features is that you can open 2 cr2s side by side and copy and paste from one to the other. but cr2 editor is pretty old, and hasn't seen an update in years, and if you dont find the right version you could well get one of the ones that corrupts files on save. I recommend cr2 Builder instead. It's written along the same lines as cr2 editor but it has far more features, and allows you to edit multiple lines at once which cr2 editor doesn't. Its by one of the japanese creators so some of the features might have you scratching your head for a bit but it is far more versitile then cr2 editor. you can find it at the link above and it's free.
