Lee,

Nobody here can make up your mind for you....YOU have to do that. Saito..OS...eeney meeney miney mo....

Either one...you're doing fine. Consider though that you've had good results with your other OS motors, they're stocked right near your house AND the dealer keeps a supply of parts on hand.

Have fun!
