I would go with the slash over the detour for sure. The detour has a very whippy backend, and the slash is an extremely versatile ball. For light, the Panic will work nicely. Very even roll, and is super controlable. For the medium arc ball, the Backyard Bully is nice, because it starts up rather quick, and is clean off the spot. The Arsenal Angulat would also work, as long as you put the pin below the fingers, to keep it from being whippy off of the spot. Hope this helps.
PS - Don't count out the Shock & Awe!!! Drill it with the MB is an arcing position, and you will have yourself a hell of a ball. Love mine to death.
