I have a 5 string Dean Pace bass. It is basically a 35" fretless neck on a stick but that stick is pretty big to emulate the feel of an upright neck. There is no truss rod on the bass. I am getting ready to change strings. The flats on there no are having a hard time holding tune. I am not sure what they are although I suspect by the red silks at top an bottom they might be GHS. I am considering the TI flats but I am concerned they will not put enough tension on the neck which may require work to play properly. Should I worry about that or try another string? I could try Chromes or even some tapewounds.
