I've bowled there plenty of times and they have AMF MAD synthetics that were installed less than 3 years ago. Traditionally, the lanes there tend to play little longer/slicker but the backends open up fairly quickly. The track tends to be 6-10 in that place. Depending on the pattern, I would likely play with angles that are a little more closed to start. An asymmetrical solid such as the Sure Lock or Alpha Crux starting out would probably work well as that can allow him to keep angles a little more closed while still carrying in back. From there, the IQ Tour is a must have as a benchmark in that house. I'd bring the urethane instead of the spare ball as that can be beneficial if the backends really start to fly and control is needed. From there, I'd probably throw in a SonIQ and then either the Wreck'Em or 1 of the Hustle balls depending on the motion he is looking for.
The other thing I can tell you is that Ryan Ciminelli drills bowling balls in the pro shop at Airport, so he may also be a good person to talk to when there in person.
Now having bowled on SPL and MAD, I think MAD holds up a little more with the oil patterns overall. But they are similar with good pin action in most cases and you'll still have a good amount of friction once the shot opens up.
