haven't seen them mentioned because i guess most of you don't live in Australia, but you might be aware of sunday hardware as the sponsor of chima, jake hayes, gabbers, dane burman, dean palmer, jack o'grady etc.
i tested some of their bearings a few years ago when they were new and sending shit out to all the shops, i think i tried three sets that all just like exploded within the first half hour, maybe even less time than that. they tried to say they'd had their whole team test them and that they'd never seen anything like that happen or ever had any feedback to that effect. every other skater/shop i spoke to had the same experience i had and got the same email back.
on another note, i once had a non-skating friend who wanted to have a go so i helped him buy a set-up. trying to teach him ollies on the spot and instead he would just do stationary front 360 ollies like knee high. it was fucking insane. but he would also explode bearings everytime he'd land {they were not sunday bearings}. i changed his bearings out a few times with old faithful spares of mine and yeah, just something about his savage impact was annihilating any bearing. so this dude was learning to skate the quickest and most impressively i've ever seen anybody do so, but he also had to quit skating quicker than almost anyone i've ever known because bearings couldn't handle him. one of the strangest days of skating ever.
