Hey sjs,
We have a few pieces that are stronger then the Freakazoid. Like Ex states, it depends on the amount of oil you want to match up to. IMHO, you can go with a Rule or Arsenal (due out end of the month) for med heavy and a GP2 for floods. This will cover the heavier side for you pretty well.
Any of our Morpheus cores or symmetrical balls (for that matter) can be drilled to arc vs snap so there's no worry there. If you decide on a Rule, let us know and the Crew here will help with a layout.
Typically the Nats do not offer a shot with free hook or hold. Your primary thoughts about arc vs snap will be the better way to go. Hope this helps....
