Ric,
I'd say that BTM tested on too short an oil pattern with too clean a backend. YOu can't take the results of every test done by BTM as the word of God handed down from on high. You've got to balance BTM's test results with BJI's (Bowlers' Journal INternational), with everyone's amatuer tests, with comments from people of ballreviews, with what your eyes see local bowlers doing.
While the Super Sonic is no doubt a strong ball for medium light oil conditions (as stated by Roto-Grip themselves), it is also a solid resin (usually meaning: earlier hook than a pearl resin and less backend that a pearl resin) and I wonder about that backend number as that is one of the highest that BTM has ever given out. Numbers are a good measure of balls' relative positioning of one against the other. AND one other thing, don't forget that BTM's backend figure is one bowler's experience (their tweener) with one ball, drilled one way (stacked leverage). The length number is also derived the same way, AS FAR AS I RECALL.
