On the tape I have for my E Caller, the Snowshoe Hare has a more raspy sound than the Jackrabbit tape. The Jackrabbit sounds more like a low pitched whaa whaa sound. Not near as raspy but otherwise they are pretty close.
I think either would work. No two animals sound exactly the same when they are getting ate by something.
Just my opinion, I could be wrong, just ask my wife /ubbthreads/images/graemlins/smile.gif
