Based upon your colors, I would first say Sovergn, PB Natty's Blue, for winter protection Collinite 476s.
Since you said that Sovergn is too expensive, the choices are PB Natty's Blue (great price, great look), or the Collinite (not that expensive, look pretty good, great protection for the winter). If you feel overwhelmed with choices, call it a day by choosing the Collinite 476s for the winter time and then revisit this in the spring. Maybe by then you can get a better choice in mind.
