2050? Are you saying you're planning to work to 64?? Wrong forum for that!
But seriously, looks good. I'm not a huge fan of the target date funds as its like active management - don't really know what they are doing over time. For instance, I'm not sure you want 18% in REITs right now, but maybe you do, either way you don't get to make that call in this type of fund. If there are Vanguard or really cheap index options, personally I'd use those. Hopefully as soon as the pension kicks in you're out.
