I have both the Thunderdome and Power Crystal and love em both. I dont use the Thunderdome much anymore because the back aluminum dome is dented in pretty badly and I don't have the right striker to get the right sound with it. I carry the power crystal every single time I go though, awesome call with the purple heart striker. Keep the crystal surface and the striker tip sanded and it sounds excellent. I used to have a black magic call and the flat tipped black striker that came with that one sounded soooo good on the power crystal, but I lost it.
