Hi!
 
I know that for the guitar folks, adding a mixed set of Gibson + Fender strings can add tens of thousands of dollars to the value of your guitar.  But I have a bass!
 
So, I love the sound of flats (Thomastik Jazz Flats, to be precise), but in 6-string sets, the upper registers lack a certain je ne sais quoi, no?  So I just strung things up as BEA in flats, and DGC in roundwounds.  So far, the experiment seems like a success.
 
Is anyone else doing anything similar?

Hmmmm Verrry interesting........ How does the feel between the A and the D Feel? tension wise i guess i'm trying to ask.. To much turkey....

It does feel a bit wonky-- the roundwounds feel more gritty/abrasive.  The transition doesn't seem so bad, though.

Flats and rounds?  
Together?  
On the same bass?  
 
OMMIGAWD!  
 
What's next?  
Cats sleeping with dogs?  
Obama and Palin getting married?  
The discovery of a three minute Grateful Dead song?  
 
Is the universe as we know it literally disintegrating before our very eyes!!!!  
 
And it all started with you mixing strings, Bradley!  Heaven help us!  
 
hehehehe
 
Hope you had a great Turkey day.
 
Bill, tgo

There's a local guy who uses a round G and flat EAD strings.  Seems to work for him.  He's a fairly simple player who has adapted what he does to make this work.

Bill,
 
I'm at a loss to respond.  
 
 
 
For those folks not afraid of a little bit of bi-(string-)curiousness, I'll try and put some recordings together.
