YoYoFactory Response Types

Hi,

can I use these in my on the way Dark Magic II or do I need to buy them from YoYo Factory?

thanks in advance for your help.

my thought was I could try different one’s or is that stupid?

DM II:

Others might fit. They don’t wear fast.

If you have to order them I’d just get the YYJ rings.

Thanks very much,

ginny
