I have flow matched 60's but am wondering if theres a point of running them at too low dc? Would running 42's at higher DC be better?

With your setup the 60's will work just fine. If you were all stock then I would go with the 42's

Don't even have to read the specifics... 60's all the way. There's absolutely no reason to buy anything smaller.
