My Wizard graduated to 70 that night, and I've been pushing her (gently) ever since. Made T16 last night.
I was wrong about which helm shard I was using; it was Terror, not Hatred. The +Int was nice, but Shard of Terror is all about cooldowns, and it just wasn't working out, since Wizards don't have many skills that have long cooldowns. I was casting skills all the time just so they'd be in cooldown, which only lasted 10 seconds or so. So once I got two more Embers, I upped a Shard of Hatred. I'd considered that one mostly for melee characters, since the damage is based on how many monsters are within 25 yards. But it's working out pretty well. I cast a Frost Hydra, then go stand on it and the bad guys come to me. They get frozen, and die shortly thereafter.
Remnant of Pain in her wand is working out nicely, too. The first one I had gave +Holy damage, but my second one rolled a raw +15% to Damage. I'm saving the +Holy damage one for a possible Monk.
After a couple of Greater Rifts, I had a banner splash a few times that was too fast for me to read; I finally figured out that I was making the Leaderboards. I was like 218th for Hardcore Wizards using Typhon's, but hey, I made the boards. It happens so rarely that I didn't realize what it was telling me.
