what response system can i use in the general yo 5 star?

on the little note it says that i can use onedrop pads but i dont know which of the two that they have now will work with it?

The OD pads you want are the pads for the original Project. I don’t see those in the YYE shop.

The Duncan 13.7mm silicone stickers will also work.

.555 sized

Gen pads?
