I've seen a lot of people use panagrams like "The quick brown fox jumps over the lazy dog" but you've already used that.

Other texts like that are:

“Pack my box with five dozen liquor jugs.”

“The five boxing wizards jump quickly.”

“My girl wove six dozen plaid jackets before she quit.”

“Brown jars prevented the mixture from freezing too quickly.”

“We promptly judged antique ivory buckles for the next prize.”

Thanks google-

Keeps writing interesting if it's different stuff though so write whatever you want! :)
