I'm the happy owner of a CR4 for 4 months now. The transition from BG to EUB was fairly painless (in hindsight). I have had issues with the tremendous amount of sustain and have temporarily fixed it with a block of dense foam next to the bridge-that's until I am able to afford the Pirastro Flexocor's Francois has suggested.
My band is very loud and when I decided to switch to the double bass I heard a lot of protesting from my bandmates. They had played with an accoustic upright player who had subbed for me and they said he couldn't get near the volume needed without tons of feedback. That's why I went with the EUB. I hear the biggest complaint from accoustic players is that they can't 'feel' the EUB. My bandmates said that maybe the player that subbed for me could 'feel' it, but they sure couldn't!!

But if, as others suggested, darker sounding strings work better on the NS, you may want to try the pirastro Originals. They are darker than the flexocors. Perhaps not as flexible for pizz as arco, but I can still get mwah with these strings on my upright by using a little more index finger knuckle.
