i recently switched to an 8.25" G027 deck after skating 7.5s in my youth and 7.75s once i started again this year.
Personally I would say stick with girl and give the G027 8.25" a go. 14" wheelbase so it doesn't feel wide or door like to skate, easy enough to move it around.
I've got it on Thunder light 148s and 50mm and it feels like an agile setup, I was landing all my tricks first time I switched up from a 7.75"... if anything flip tricks are easier to catch and the board spins in a slightly slower and more controlled way.
I skate 80% flatground with about 20% banks and ledges when I get to a park, and it's a great setup for this... if I was a little more flush then maybe I would have gone with hollow lights, but it's a nimble enough setup as it is really, 2.3kg odd.
As for quality, this is my first ever Girl deck, and i'm perfectly happy with the construction and how it feels... I've been skating Generator decks for the last few, and the Girl doesn't feel like a step down.
TLDR try the G027 8.25" Girl decks.
