If you really, really love the style of the tote, and don't mind having two bags from the same ligne in the same color, then by all means keep it... or you could always get the tote in a more neutral color (black, etc.), so that they're not so similar.
The straps on the tote is much longer, then on the satchel.
I tried the tote on way back in the summer at a trunk show. Am I the only one who felt like it weighed 50 lbs? Not that I don't love the way it looks, but it just seemed so heavy.
