I believe I just saw Mika throwing this ball, the Track HX05, on the PBA League TV show. (It was purple and gold coloring like this ball seems to have, looking like the pictures I have seen.)
so, if Track were following the old naming conventions, would this be considered the new 505A?
I ask this because -
It seems like it has the same core as the 5050C2, but the coverstock, also a pearl, like the 505C2, seems to my eyes, with Mika's delivery, to have a more pronounced backend.
