I've also done a ton of experimentation, and I disagree that the worms have anything to do with demosaicing. I'm going throught the same process and now turning everything off in x-transformer. I find Iridient's default setting oversharpen and are super "crunchy". I had been using “default settings”, whatever that entails, so apparently it is time to change settings. If someone can do better on different software, I'd very much like to see it.

It really quite simple, not much extra work at all. Then I can finish editing and add sharpening and NR (different than what I would use in LR alone). In Lr, after I've gone through them, usually cropping and pre-editing as I go, I will select the keepers and just process those through X-Transformer, all the cropping and editing carry over into the DNGs. I always save the original RAFs (you never know what better processor might come along). The worms are not a product of LR sharpening, they are demosaiicing errors that are accentuated by sharpening. If you use it correctly, it works just fine with properly demosaiiced files. Do all your NR and sharpening in Lightroom, yes, I said Lightroom.

I also let it handle the lens corrections, which is identical to LR. You want to just use for its superior demosaiicing algorithm. Set it for MORE DETAILED (actually doesn’t make much difference), Set the Iridient Sharpening and NR to NONE, it just changed with the last update, but it probably still sucks - it adds all sorts of ugly artifacts, particularly at high ISOs. I have done extensive experimentation with XT/Lightroom and have come to the same conclusions as some others who've been at this a while.
