I liked Qualityy simply because you could tell somebody how to spell it in one sentence, Quality with two y's. Though, the greater pun is how quality can qualityy be if it's misspelled. And I think I heard somewhere that two of the last letter of a word can make it brandable. I thought Sponzori would have been great for anything sponsor related but according to BB, and you it's not as much of a brandable as I thought.
I appreciate your feedback, it helps solidify the rejection. I had placed some hope in some 5-7 letter words in different languages, though they too were rejected.
