If I was working with your animals I would go for the pastel lesser. IF you produce a male pastel lesser you could still shoot for super pastels, or super pastel lessers when you raise that male up and pair him back to your pastel female.
You could also pair that lesser up to the female normal, tho that pretty much phases out the need for your single gene pastel male.
If you produced a female pastel lesser you could hold onto her and grow her up for your pinstripe and shoot for pastel kingpins in the future. Or if you still wanted a super pastel you could probably easily trade a pastel lesser for super pastel. Whenever your pinstripe does reach size you could get lemonblasts by doing pinstripe x pastel.
Generally having the superform of any codom gene is a plus cause it eliminates normals, but unless your really wanting to produce super pastels then that single gene pastel male might end up phased out of breeding plans unless you get lucky with a dual sired clutch and get super pastels and pastel lessers from the same clutch.
