I've seen Michael post on this a few times Brian. Boolean is a way of life in NURBS but in Poly it's almost a No no. Seems it never follows down road well in a poly modeler!

I dont think theres a tool to twist that in MoI after it's created, but could you use a Helix as a path to array your original boolean objects to be twisted?

I'll poke around with you and see.
