In 2012, 89 cases involving discretionary review were submitted to the CCA for decision (not counting companion cases). Not sure how often oral arguments were requested under TRAP 68.4(c), but probably in more than the 28 cases (31.5%) in which oral argument was permitted. For those who have succeeded in getting such a request granted, would you be willing to share the statements regarding oral argument that you included in your petitions?

"Undersigned counsel promises not to cry or splash fake blood on counsel table this time."

Having argument granted likely has more to do with the case itself than your statement regarding argument. But in case it helps, here's the one I used in a case where argument has been granted:
"The State respectfully requests oral argument. Like other Fourth Amendment issues, the main question at issue in this case—whether the officer had reasonable suspicion to conduct a weapons search of the car—will likely turn on a number of particular facts. Oral argument is especially suited to crystallize those facts that matter most and test the competing policy concerns of individual privacy versus officer safety."
