Aquila 85U Red Series Concert Set

First of all, these aren't bad strings- they're okay. Nice clear, crisp sound. I have 3 problems with it:
1. They're really thin. Or at least they FEEL really thin. It's probably why they have such a high-middy sound. If you want to record ukulele with other instruments, that could be a good thing for the mix, but if one of your main focuses is the uke, a bit beefier sound and feel would be better I think.
2. They feel unnaturally slippery. Comfy for sliding around the neck, but a bit weird on the picking hand for fingerstyle.
3. My biggest problem with it is that it's super SQUEEKY. When my fingers slide a bit on the strings they have this really unpleasant high pitched plastic noise. Sorta makes picking with your fingertips a pain to listen to.

So if you're just strumming some chords and want the uke to sit well in a mix with other instruments, these strings can be good, but for me personally, they are just weird and squeeky.
