both rubiks.com diy's are good choices, but why six sets of pet stickers? you should just get their pvc stickers... they last forever as long as you don't pick at them.
I've never needed my second set of pvc stickers, but i have had to replace a set of pet stickers on another cube, but it was due to me forgetting to trim my fingernails and thus, peeling stickers way too quickly.
And, sidenote... couldn't you get both for the price of six sets of pet stickers... and some lube as well (even though it is only helpful for a few days)
