I'm going to be making the same exact pairing this fall and plan to hold back all of the female spider het clowns and sell everything else.

My reasoning is that hopefully I will also produce a male pastel clown from my clown to my pastel het clown female. When the male pastel clown and female spider hets are up to size I can then try for bumblebee clowns. Of course that's all assuming everything goes exactly as planned
