It's been ~10 years since IPv6 became "ready for prime-time" and I wouldn't touch it unless I absolutely have no other choice. In practice you are going to run into bugs and problems at every level, from client software to the OS networking, your router, your ISP, their ISP, their router, their server and so on and so forth. I absolutely support other people using it to iron out all the kinks, so that I can finally do it without headaches in 10 more years.
