Well, this isn't exactly a product question but i'm not sure where else to put it. But theres one thing i run through bicycles too fast. Where i live we can get bicycles for about 1.75$ ea. So those are the cards i use to practice. But after 2 weeks of use i just don't like to use them. They are kind of bent and dirty. I do stuff to wash them they just don't feel the same. I heard studs are good, never used them though. But are there any cheap cards that really are good? And last a while? Thanks guys.
