For the cost, if you're going to get the front hoses, you might as well get the back too IMO.
That said, the back is a bit of a double edged sword. As I'm sure you're aware, it's all too easy to lock the back of a bike up. Putting braided hoses on the SV increases this chance of lockup. Can you remember to use less pressure on the back end (even if only marginal)?
If you can, go for it.
Oh, and welcome
