The Rastapants are fairly cheap, and their responses seemed good (http://www.head-fi.org/t/452404/just-listened-to-some-fostex-t50rps-today-wow/4185#post_7845429) although I haven't found any reviews of them. The Thunderpants are regarded pretty highly and look sexy as ****. The Koda^2 look interesting but they seem to be the most expensive. I want to use these for metal.
Some people have owned the modified T50RPs with wooden cups and have felt that the additional cost did not make up for an equal improvement in sound. I will have a pair of Maple-cupped modified headphones next week to compare to my "treated" T50RPs with the standard plastic cups. I'll run through various genres of music and utilize my O2 amp, my C&C BH amp as well as my Sansui 881 receiver.
There's a modified pair of Fostex T50RPs on the F.S. section here for about $200, I believe. However, the wooden bowls have 3 total cracks in them. Since the wooden bowls are a larger wooden surface area, I'd imagine that keeping them from cracking due to humidity and dryness fluctuations would be a never-ending process. Just look at how Hifiman has converted their headphones over to plastic rings for the outer cup areas because when they utilized wood, many buyers experienced cracking issues.
But, based on my experience of the T50RPs so far, I'd opt for the $20 - $25 in internal modifications, then work on a new cable - about another $20 using Mogami quad cable and then check into some of the pad replacement options. Get those in place and call the project "done." With the money that you will have saved, spend the money on an amp or some more music to enjoy. To me, the T50RPs in their plastic housings look like "sleepers" and many people won't be keen to what's under the hood ... er, what's inside the cups. They're not a blingy headphone or a Blows headphone, so theft risk on them would be quite low.
Edit: I have seen the pictures of the Koda^2 headphones. I think they've done an outstanding job of incorporating the driver and the side headband pieces into cups that look like multi-layered wood circles. I suspect the Koda^2 would weather out the changes in humidity much better than a pair of cups cut from a single piece of wood.
