>slide throttles... pros & cons compared with butterfly throttles?

One advantage is zero flow loss when a slide throttle is wide open:
there is nothing left in the flow path. A con would be constructing one
that doesn't leak with the room available in the engine bay; it has to
slide SOMEWHERE. I have seen barrel throttles, which is basically 100%
shaft with a hole the size of the bore, sort of like certain kinds of
hydraulic/pneumatic valves. They don't need that much room and also
provide zero flow loss at WOT. You can DIY anything given enough
patience, time, money...
