Alternative HSpin Pyro Response Pads

I own an original HSpin Pyro, I have never been happy with the response used in this yo-yo as it relies to much on having fresh string to respond properly.

I would prefer something that is long lasting that binds well, yet allows for unresponsive play.

I see that yoyoexpert carries Dif-Pads which should be a direct drop in replacement, but what alternative response pads are available from yoyoexpert that will fit my Pyro?

Dif pads will work. Also you  can use the 13.7 mm Duncan silicone pads.
