I play baritone ukulele and also have preferred the Aquila strings and have found the g string breaks most often. This has been wwith any type string though. I just got a new ukulele and I have a set of KO'OLAU GOLD STRINGS on right now, but I think they sound a bit dull compared to the Aquila.
I'm having a new pickup installed and I'll go back to the aquila.
Cheers
