Interesting EW double?

It's interesting to note that there are a couple of 3-1 shots in the 2 big hurdles races that have won 20/22 and 19/20 of their hurdle races respectively (you know who they are). One has run the race he is contesting 4 times, the other twice. Neither of them have EVER been unplaced. Not once, ever, in 6 years of top level competition. An each way double pays around 15-1 on the win part and 6-4 the places, giving you a 50% profit on stakes for 2 thirds. Just saying.
