I've tried everything, from taking the suit magnets out, moving them, and just having the small ones under the cowl with the clips on top, just about every freaking combo you can think of, and ultimately I hate it all.
'Cause just when you think you've got it right, you breathe on it & a magnet jumps out of place onto the other magnet & you start from scratch all over again.
If they had the magnets in the right place under the suit in the first place it would be ok, but it's not easy spotting them in the right place under the suit because the little circles get in the way, or the padding under the suit gets in the way, or they don't sit on the cowl right, and I don't want to to dig around in there too much for fear of ripping the suit. So I said **** it, took all the magnets out, & used glue dots to spot the custom cape in place under the cowl and another pair of glue dots under the clips too. That way everything goes where I want it nice & easy.
I curse you, evil magnets. Do not live long; do not prosper.
Regarding waist articulation...it does have front to back and side to side. I haven't tried twisting it...and probably won't.
I have 420+ reasons not to push my luck on this thing.
