I would personally have vanilla some where in the males genetics for this pairing. Super pastel does grant the minimum lowest possible odd of always being pastel for offspring, though there are many other options available than just super pastel, unless that is the route you are adamant on going. The morph market has a list of genetics and when selecting say vanilla will bring you a side variety of different animals carrying that specific gene alongside of many combos, with spider being involved stay away from champagne in whatever you may decide to go with. Good luck on your decision and hope you have fun lookin for a suitable male.
