I've skated two P8s back to back, probably my favorite shape from them hands down. If you like a Square tail that's not
too square and a PHAT round nose then it's the one for you. Pretty much just fall asleep on top of crooks til it's time to come out.
I also had a P9 after those two. Makes flip tricks very easy but the square tail is still there so all your tricks pop nice and even.
Would love to hear what that Arigato shape is like, is it just a smaller P8?
