I'd recommend that you start with a laminate (dymondwood) and purpleheart....they are very versatile for all surfaces...once you have a couple good strikers that play most calls well you can always tinker to find "the one" for a certain call or surface.
My favorite and most versatile strikers are:
(1) woodhaven oak laminate with flare tip
(2) dymondwood from Lights Out game calls
(3) purpleheart from Harold Fowler and Russell Beard
(4) hickory from Houndstooth game calls
(5) black locust from Harold Fowler
I hope this helps. As others have said, every call and caller have their preferences, but you'll probably be well served with dymondwood and purpleheart I think.
Good luck!
