ive rode s&m 30" bars, they feel huge, but really nice, very easy to spin.
dont get fly cranks, the amount of times i have seen these snap at skateparks is unreal.
if you want a good strong reliable crank, go for proflies ( i have these ) or hollowbites. illigal cranks are good also and so are eclat.
i have one of the first sunday funday frames and its amazing, short rear end makes it very easy to control and spin. i also find it a little easier to tailwhip it than other frames?
propper ttl frames feel very nice aswell
but as with any frame, it depends if you want to ride street, park or dirt
