I wouldn't consider Ksyriums at all. They are not aero and not super light, so I do not see why they are so popular. I rarely see someone break a spoke on a ride, but every time I have seen a broken spoke during a ride it was on a Ksyrium wheel.
Running an aero wheel is not necessary. Apparently it is the popular thing to do, but square frame rims allow for more shock absorption and the blade spokes are nice. the EA50s are not bad, but they're not great either. Personally if I were to go aero I would to at least an EC90+ else not bother. Weight on the EA50s are not that great either, keep what is on there until you have enough for an excellent wheel and keep what came on the bike for training. Biggest thing about Aero wheels for me is the cross wind factor, and thats not fun.
