Authority

I sprayed some authority this spring in front of peas and have only had one little shower about three weeks later, anyway it's not working as well as it should. My question is about going back to canola next year, if it stays dry am I going to see some residual damage on my canola next spring? I am trying to decide on viper or odyssey, it would be nice to plant canola next year and straighten the field out. I have sprayed both odyssey and viper in the past and have always been way happier with odyssey. Or maybe there is another option?
