You realize I'm the guy who posted those ex puddle armor breaking setups, right? I know what I'm talking about, and I know what I've done. Don't dismiss what I say out of hand, please.
Try f34, d1, f34, 212~db1 in the corner, making sure to hit 212 as high as possible, then break with s1. The best I've broken is 15 frames, traded with 14. I can consistently break 17, and it works in all variations. If you use ex puddle like this, Lao's spin gets broke really easily with s1. So on slower armors, you can use slower moves like 212, f11, f44, etc and still break for ridiculous damage.
