The advertisements for the original Triton Heat did indeed list the differential as .051. But that was never the case. When I worked at Ebonite, we did testing of competitive products on a regular basis, both on the lanes and in the lab. In the lab the ball was spun to find the PSA, then swung to determine RG's and differentials. This ball was of particular interest to me. Through my time as a tour rep, I got to see many of these being thrown, with various drill patterns. The overall flare of this ball was nowhere near what a ball with .051 diff would be. When we got it back into the lab, it was confirmed that it did not have the same diff as was advertised. Not that it mattered to all those who had one and kicked some serious butt with it (and made my tour rep life miserable).
Lower differential balls can be drilled stronger without having the tendency to burn out in the backends. The Heat was one of the most popular balls in the history of reactive resin products. Its versatility is its main attribute, and the lower differential contributes to the versatility because most bowler styles can drill it strong and be effective. It is not, nor ever was, a ball for heavier oil. It is one of those "smart" balls that does what you tell it to do. Changing release positions will result in the desired reaction.
