I have the Soul 3.0SL that you are considering. They are fantastic. Over 2000kms on them and still rolling perfectly true. Those Prodigy hubs are amazing - they spin forever.
That said, if you're looking for a quiet hub, you will be disappointed, as the Souls are quite loud. Just don't coast
I highly recommend them. Not to mention Sean @ Soul is awesome. Excellent communication from ordering, building, to shipping. I'm considering some 4.0's next year.
