11x KC Pro TeeBird. And are there different runs or are they all the same? (X vs L)
Depends on pearlyness, condition, weight (the heavier the better)... There aren't really different runs like x and l just CA and CAL but all my 11x Kc Pros are CA but my 11x (Non Kc Pro) are CAL. My 10xs are Cals as well.
