Because for a person who has skated as long as I have. I know what to look for in a deck. if you are like me and sick of boards that chip and break in the first 2 weeks of owning the deck, than you will love these boards. they keep there shape, and very strong. I have had my 8 for about a month and it still has same pop and shape as when i first put the trucks on the deck. so if that answers your question. if you have any more let me know.
