I will disagree with Graham regarding the multi slots being needed for threading. I do a lot of threading, in fact I have just finished making 30 or so pullstuds for my mill and the threads are perfect, also a month or so back I made a load of pullstuds up for Brett (Chaoticone) and these too were perfect, same with the toolpost bolts I made, the prop shafts I have made and so on. The largest thread I have done so far was 2.5 inch BSP and the smallest thread I have done was M4 so maybe if you go ultra small it will be a different story but I dont think so.
My spindle isnt controlled by the Index pulse however as the spindle speeds on my Lathe are controlled with Electromagnetic clutches, possibly if you have the speed set and controlled from a VFD a multi slot disc might be better.
