As much as I hate to agree with FFS on anything...
I've looked at a lot of slow motion videos concentrating on spin.
The fastball and the drop ball have the same spin. (My disagreement with FFS is that a good drop ball pitcher can achieve greater spin rates on the drop as opposed to the fastball.)
As to the rise, curve and screw...*most* pitchers throw all three with the same spin (bullet).
There are very few (almost none) pitchers throwing a rise with 6-12 or 7-1 spin.
I've yet to see any pitcher throw a curve or screw with anything remotely resembling the spin achieved by baseball pitchers.
