Uh, no. Kelme's fall apart way too fast.
I've had f50's. I liked them a lot last season, and I have heard people say they lose studs a lot, but I never lost one. They're light and pretty good about breaking in. The touch is realllly nice on the toe, but I don't like how narrow they are.
Pumas are always a decent choice, but it really depends what you're looking for and how long you want them.
I'd say Pumas if you want to use them more than a year, f30's if it's for one year.
