I tried the oasis smooth wound when they first came out.
I didn't like them. I initially replaced a freemont soloist with it, because at the time i was on soloist/oasis.
The oasis ones are not nearly as smooth as the soloist. Also, the tone wasn't just bassier, but darker and a bit dull.
But the deal killer for me.. is that they seemed to separate in the wind at the nut.
Tuning over time seemed to pull the windings and expose the core after a few days.
And before you say I needed to file the nut, the soloist and the TI's didn't have that issue on the same uke.
This happened on both of the oasis smooth wound G's I had, so I stopped buying them.
I've been much more satisfied with the TI's on the 3rd/4th... sooo good.
Even tone that doesn't stick out. Very not in your face for wound bass, yet still good projection
