Sounds like we are in the same boat financially 3nenbgumi. I figured exactly the same as you. I also totally get what you say about voluntary ex communication from Headfi. Surely this place cannot give my wallet any more of a kicking?! Actually, I suspect it can!
I just have pain in one spot. The left tragus. It was difficulties with that that lead me to customs so I hope it can be solved. Other than that yes surprisingly comfortable. Probably better than the silicone custom tips I use with the T 15's. I envy you getting a perfect fit straight off.
Regarding re shells. Iirc there was some discussion of that a bit back in this thread. Apparently UM claim that they replicate the Freqphase positioning. I would think the re shell would be fine. At worst you would end up with a non FP 13. It depends if the extra funds are really not available.
