As the (slate type) calls go i am most parcel to the glass, crystal top calls.
I usally carry two a primo's power crystal and a H.S.strut T-glass.
Both are good calls,but of the two the primo's is by far my favorite.
None of the strikers that came with these calls were to my liking but i have a Hickory (thin) striker that sounds great with the primo's.
Any small diamater hard wood striker should be good....even hardwood dowels from the hardware store will work....just have to play around some with lenght and size.
