figured I'd ask this here before the mechanic forum since quite a few people seem to know about these hubs here. i found a set of used high flange DA hubs for really cheap online and basically dived in before getting a good look at them. they're slotted for bladed spokes and seem to be pretty worn. now, i'm kinda wondering if they're safe to build up...any insight appreciated. here's a couple of pics.
