I'm looking to ask if I should get Vue D'Spirit 4 or 5? I'm getting Vue for the first time and I like the $69.00 price tag. But is 4 still good? Will I see the difference between 4 and 5? I downloaded the trials and they seem the same. If I should get 5, then why? I have P5, D/S and Max. I wanted to add Vue to my toolbox but money is tight, and I made a mistake by buying Bryce. Thanks ahead of time.
