Silver Streak x Silver Streak ?

What would be the aprx. % & outcome of the clutch when breeding a silver streak to silver streak?
would it be?
25%silver streak
25%black pastel
25%super pastel
25%super black pastel
or would their be pastels too.
or would you just get all silver streaks?

You would get

25% Super Pewters
25% Super Pastels
50% Silver Streaks

Thanks. I almost put 50% silver steaks on there but then I thought that the two Black pastel genes one in either parent would have made SBP, but thats where the Super pewter comes in because of the pastel gene. right?
