The Tank is definitely good for short patterns. And it is pretty similar to the Super Natural. Also, believe it or not, but the Arctic Sniper is also nice. The Tank provides more length and more backend, but the Sniper will get into a smoother, early roll - more like traditional urethanes. You just have to make sure you let it roll or it won't work. With both, I find that I usually need to be pretty flush or light if I want to carry the corner pins.
As was suggested, the Apex is definitely a great option. A little more forgiveness than the Tank on outside misses, but if you pull it and the hold isn't there, you could be in trouble. That said, if he doesn't like urethane, the Apex is the way to go. He could start with that and stay more to the outside. The Tribal would be good if he has to get deeper and swing it out.
I also tried my teammate/pro shop guy's Rude Dude last night after league. Those lanes hook a lot to begin with and this was on the burn. I know he drilled it for length and less hook (luckily most of our specs match up), but I was impressed with how straight I was able to play. My Motiv stuff requires getting deeper and sending it out - usually with speed. I threw DV8 for a little while before throwing mostly Motiv now, and I did find most of their stuff to be a lot more arcing than Motiv balls. So he may find that the Rude Dude also works.
