I know first hand that Rudals throws down.
As far as the stripes:
Two of them are navy base. You have enough navy ties for your gray suits, and since you prefer navy suits, you'll want to steer away from navy ties.
The blue in the other striped tie is light enough, but I'm not keen on stripes the same width. This might be because I struggle with them (and because they suffer a bit from "neither this nor that")
