First of all I can see why you would say that its a bit redundant. You can definitely have a sense of my taste.
Second, I am a player and not a collector. If I was a collector, I would pick something that gain in value. And I'm still wondering how is that suppose to make sense since I like them equally. I think we all know how consistent Roger's basses are.
They also have different wood.
Sometime I will play one of them for a few gigs and I think "yeah, That's the one" then I play the next one and I feel the same way.
As far as neck profile. I like the Will Lee profile a little better but hey! I own a couple of old Fender P and I love them too (but I think Its the tone more then the neck). My point is, If I like the tone of a bass, I will play it regardless of the neck profile.
There lays the conundrum. I love them all too much and they pretty much get equal playing time. Therefor my request for help deciding.
It's definitely the best problem I've ever had.
