I got me the Primos Power Crystal, and when I roughed it up, I wasn't thinking and did it in circles, then remembered and roughed it up all over in one direction. First, will I be ok in those circular spots over time as I continue to rough it up in that same one direction?

Also, it seems like I have to rough it up every few series of yelps to keep the sound good, meaning I'll be doing it during hunts between calls sometimes. Is it normal to have to rough it up this often?

Thanks for any help you can give! By the way, I find the rosewood strikers to sound best on the crystal.
