Kala-SLNG Aquila Strings

I want to replace my stocked strings on my Kala-SLNG ukulele. It is a long neck so I was wondering what size strings to get. I'm guessing that I need concert sized strings since it is a long neck but I just want to make sure before I buy some. Thanks

Depends, I dont know the model but I've seen sopranos with concert and tenor necks.

How long is the neck?

Well I guess its a soprano ukulele with a concert neck so I'm guessing I need concert strings?
