They'll work..even a rusty rod will. You can practice technique. Unless the flux is falling off, you can still practice. Even if it is hard to start an arc, you will get better at arc striking.
That's what got me where I am. I bought about 30# of rod from a garage sale and ran half of it through my old Montgomery Wards AC stick welder sticking horseshoes, T-posts, and other scrap together. When I got new rods and a better welder, I can strike an arc with the best of them. I can make metal stick together now too.
It's not the easiest way to learn, but it works.
