I'm having a hell of a time stuffing the tmz's down my omega, do I have to go with the harvester yellow (for the boat tail) or can I use the harvester black's? Does the .0055'' make that much of a difference? Am I way off and you can't actually switch a flat base and a boat tail sabo? The local target shop has the black crushed rib sabos in stock otherwise i'll order up I guess.
