I remember when the D'Addario half wounds first came out. It was all I'd use. They are still great strings, my taste in sound has just changed a little. I like a little brighter sound than the D'Addarios give me.  
On a side note, just to show how confusing the English language is,wound can be, I have a bullet wound in my leg or these strings are round wound.
Or how about, THEY'RE going to move THEIR stuff over THERE!
Things that make you go HMMMMMM!

We're going to move Weir's stuff over where?

Where did Steve go?

Olie, are you going to unwind that bullet?

Interesting Ollie -- I like the half-wounds for the exact reason you have chosen others. I prefer them because they are not so bright! One man's pleasure....

Cosmic-
I'll go one step further.  I've just replaced the halfwounds on my fretted bass with flatwounds.  I love the sound I'm getting.

I put on some D' Addario XL rounds and am really digging the sound of them. I work at a music store, so I'll be trying some different sets in the next few months. Thanks for all of your posts and suggestions.
