I am making some flat Pokeballs to go on top of some buttercream cupcakes.  Which will hold it's firmness better-Fondant laced with Tylose powder, 50/50 fondant gumpaste, or pure gumpaste?  I am trying to keep cost down and initially thought the fondant with Tylose should work but am now having second thought so I'm asking the experts! =-)

If you make them a few days ahead, any of them should work

Thanks!  I ended up going with the fondant/Tylose mixture.  The party is Friday so I hope they can harden well by then.  =-)
