This is not an inappropriate usage.  LSTM is difficult to setup correctly, but 
RBP should work without too much difficulty -- it does require attention to 
the appropriate architecture and parameters.  You might want to just start 
with an SRN (just add a context layer to a feedforward backprop net -- the 
wizard will do this for you) -- it is the most foolproof and will work pretty 
well, but not as well as the others.  This will give you a quick first-pass 
sense of whether there is any regularity at all.
