Well, there are few that I can think of. To start off, you may want him to get in contact with the Managing Director of Seismic Bowling which is Ryan Press at ryan@seismicbowling.com
What I can tell you is that after being in the business for over 20 years, I truely haven't seen a more complete arsenal by any company other than Seismic. The balls roll real good and the carry percentage is phenomenal.
Also, Seismic doesn't come out with a dozen of balls a year. This is good for a proshop, you don't have to mark down your balls when a new one comes out every month or so!! Most companies have 1 or 2 really good balls in their year (thats out of 10 or so), so that means a customer has a higher percentage in buying a ball that's so so from lets say the big 3 companies. Everything that Seismic does is thought out to help the bowler score better on different oil patterns.
The covers which are poured a 900G are user friendly and they have an incredible longevity (I still have an Epicenter that has over 200 games and 3 years).
Hope this helps you out, PM me if you have other questions.
