Envy 64 Pad Response HELP!

So, what are the best pads for it, I was thinking of getting Thin hat pads and Barking Spider Gummies but what would be Best, Noel told me Any pads but I don’t want to pay 6.00 shipping for response pads. I really need Alchemy string so pads that are availble on a site that sell that would be great.

This has all ready been answered why ask it again  ???
