Which kind of bedding is better for my hamster?

It's getting hot and I use to use pine bedding but it sticks everywhere, it is however comfy to sleep on. So should I buy xorncob or something like that I don't know what it was but it was like dried corn. I'm really nit sure if it's even called corn cobs cause I know what thy is and it deffinetly doesn't look like it. Anyway would that be better it's like mini and kinda hard but I think that would be cooler for them. Seems hard to sleep on yhough. Should I switch. If what asking isn't clear enough then tell me an I'll prove my question. An get link to both beddings. :) thankssssss from now!!!
