My Clara (used) came with high-G Aquila Reds which sounded and played great. Looked great, too. I switched to low-G Oasis Brights (with a wound G string) because I wanted a low-G concert. It sounds and plays great, though it doesn't look as snazzy. The Clara's super-resonant body can punch a low-G better than most concerts. Which suits me, but if it's too punchy for you there are lots of options.
Is this your first uke with low-G ? It may be the low-G is standing out like a sore thumb simply because it's different from what you're used to hearing. Maybe you'll get used to it, or maybe not. Another possibility is that your strum is at an angle that hits the G string harder than the other strings. A wound low-G sits a bit higher and it might be catching your fingers. If you play the Clara for a while and make a point of aiming at the C, E and A strings, it might start to sound better. It's a subtle thing, but we all make tiny corrections to our playing technique and every new uke, tuning and set of strings requires some adjustment.
Another option, as others have mentioned, is to try different strings. An unwound low-G might be just the ticket. Nonetheless, some people never do get to like a low-G. That's OK. Your Clara will sound wonderful in high-G tuning.
