Size determines volume and all other things being equal, smaller will be higher in pitch. What you're really after is a heavy cymbal because they're the pingiest of all. Dry refers to how much sustain it will have. You can have larger dryer cymbals that are thin and therefore won't have as much ping. Since you're looking for dry and pingy, I'd suggest something heavy for sure. I'll second any of the Sabian RBDRs as they do that really well and have great sounded bells. I'm not as familiar with the Paiste's mentioned, but I have no doubt they'd do what you're looking for. Anything that says "power" or "metal" in the name will also likely do it, as will any Zildjian Ping ride, though I don't know if they'll be as dry as you want. I had one many years ago and it was definitely pingy, which is all you're going to hear when playing with a band, and if you're band is loud enough, it won't matter nearly as much how dry the cymbal is since whatever wash or spread is under the ping gets consumed by the music anyway.
