Agree with Gareee here, I also have Bryce 5 or 5.5 can't remember which but haven't bothered with it. The shear scale, versatility and stuff I still need to learn with Vue6Inf is mind boggling!
As you have a previous version of vue could you not upgrade to 6Infinite as this gives you so much more than Esprit could. Yea I know it could be a money thing, I'm maxed out so can't get V4 at the moment [LOL].
Good luck with whatever you decide!
