I'd say Diego as well. Doesn't have a weakness in catching on either side...ditto for rebotes. He is also pretty consistent. Solo runs so hot and cold. As far as Arriaga...his singles game is still top notch, but his doubles is eluding him right now...then again, he was out some time with that injury. Erik gets a shit load of free points in the earlies, and I can't judge him well enough until they stick him in lates, permanently...then again, Dania tends to love to have a good frontcourter in the earlies. They did it with Foronda, too.
