Nice!
As you know, I re-potted mine a few weeks ago, and it is happy as can be (Thread linked below).
At first, a few of the larger leaves wrinkled; but I've been sure to water consistently and to
keep this recuperating plant in partial shade. I lost two leaves after this re-potting, which is
far better than past re-pottings! Yellow leaves mean too much moisture, but that's easy to correct.
Good score!

I was worried about loosing the whole plant and didn't trust myself to botch the soil-less mix... But they're both recovering well. I was definitely inspired by your post!
