Why sponge thickness do you use and why?

Real men play TTX with wood bats in some honky tonk somewhere like Cut Bank, Montana, where the barmaids have tattooed forearms bigger than Popeye's, the quarter a play juke box doesn't work most of the time, and the Friday night house band does their thing behind chicken wire.

Do you mean to tell me with all gravity, young man, that Cut Bank, Montana, honky tonks, barmaids with tattooed Popeye forearms, juke boxes that won't take your quarters, and house bands playing behind chicken wire don't exist?  Forsooth and gadzooks, stripling.

I'll make you an offer I'm confident that you'll be real man enough not to refuse.  You make up a story. It has to be table tennis related, and it can even refer to maximum thickness sponge, and your manliness in being able to employ such dangerous material with I presume some degree of effectiveness. I do hope, however, that your manhood does not depend entirely upon the thickness of the table tennis rubber you use, and that other factors come into play as well.

For the record, when I used sponge, from BTY D-13 1.5 mm. to Bryce 2.1 mm. back in 2005, nobody brought up the subject of manliness.  If the other guy had a Tec-9, you used a Tec-9 too.  If the other guy were to come armed with a rapier, the Code of the Hills required that you meet him on the field of battle similarly equipped.
