So I got the TI flats, and they RULE!

(Props to JimmyM for cluing me in.

)
But the low-B is relatively non-existant. Can't say I'm surprised, considering how light the first 4 strings are, and then... BAM! .136" low-B. When I up the treble or add gain to clear it up and bring it out, the other 4 strings become too obnoxious.
Anyone use different types of strings on the same bass? I'm thinking of throwing a Ken Smith tapered half-round or tapered compression-wound low-B.
Any other ideas on balancing out the low-B with the rest of the strings?
