For the record the wheel will get as straight as the rim is, the guy who build them probably got a lot of troubles with the front one and if the rim is not in good condition and there u have the issues. Between spoke 10 and 11 u have a lot of difference, thats might be the rim joint (expected tho), the funny thing is that at the opposite side (valve) u have the same problem. The rim was used or new?

New rims can be really bad sometimes but all depends of mere luck. The other thing is the builder's ability. If that was my wheel the 1st thing to do is to just start truing it again and putting some lock compound in the threads that are messing you up. What u can do is to use oil in every spoke thread and retrue the wheel as much as possible.

If you are in DC i can take a look to your wheel if you like.
