Gee, Stratovani, glad you like them! I put them on a Rogue
VB-100 bass (pictured below).
The factory strings on the Rogue were tiny gauge and sounded thin and nasty - I despaired of whether the instrument would be usable. But on a best guess, I bought the Hofner flats and installed them - and they completely transformed the bass. Now it sounds and plays great! Plenty of depth and a nice, rich sound.
A couple of years back there was a long comparison thread on another forum (dedicated to Fender, nudge nudge) where a member tried three or four of the inexpensive violin basses - I'm guessing, but I think it was Douglas, Epi, Rogue and one other. They all sounded similar, all had good workmanship, but the Hofners made ALL of them sound better.
And yes, in my experience Labellas (and most flats) need a few weeks to settle in, and then you're good for a couple of decades before you need strings again.
Enjoy!
And Dave - good to know about the TIs. I've shied away from them based on cost, and haven't had problems with the Labellas breaking. Maybe some day.....
