The Implosia booleans are great if you can manage to build a bug free network but Implosia is definitely on the flaky side. I hate to say it but Houdini is the best route forward. The new booleans in H16 are rock solid and it's child's play managing the Redshift shading network (no extra charge to use RS in Houdini).
