i hate new string sound - i play my rounds and my flats for at least a year once i find the type that sounds good on each bass. i have definitely tried strings that i didn't like after a couple months, and in those cases it was time for a change.
I'm divided on that...
I love zingy new round wounds on my Stingray and my Jazz and Precision.
However, I have 2-year old rounds on my fretless and they sound wonderful on that bass. I dread the day I have to change them.
