Go Radial
Tied and soldiered is very cool looking and very oldschool, I always wanted a set of wheels like that. that being said I don't think you can just get some small safety wire and go to town. you would need to detension the wheel and start from scratch truing and tensioning. then when the wheel is nice and tigght tie it.
