which size pads? and bearings

are the protostar and dv888 capable with .555 size pads? also whats the difference between a large bearing and small bearing dv888

the protostar and dv888 have slim pads or 888 sized. small bearings and large bearing yoyos are different because they have different bearings. small bearings are smaller bearings ussually a sized and spin faster. but allow less string layers. large bearings spin slowwer but still pretty fast and handle more string layers.
