So, if you want to keep the bass stock, go with Classic Vibe all the way, though I really like the VM jazz neck because it's satin and my hand just knows its way around on it.
The gloss finish on the CV that I tried today was just too sticky for me. I had the sales clerk clean it for me and it was still a drawback. Sound-wise, it rocks, but so did the VM IMO. The VM was just a tad thinner sounding, but not by much. Tough call, and I'm sure I'd be happy either way, but it's the VM neck FTW.
I have gigged both (CV and VM series) but love these classic vibe basses and don't mind the glossy neck. Honestly, for me the bridge upgrade and attention to detail make the CV basses more "worth it" to me, but thats IMO..
