Thank you for the quick responses.
I guess I'll have some time to think about T5 vs T10 and keep my eyes open on the forums for anyone who has/is purchasing one of these cages.
As for the type of ball, well that's completely up in the air. I'm not getting my heart set on a specific morph until I'm actually looking to buy. Will find a breeder who has a few young ones that I like then pick from there. But loving pretty much anything with a spider pattern, the GHI's always catch my eye and the banana/coral grows are just gorgeous. Of course when I see any morph that is black/white/gray I can't help but be drawn to them. So I don't know. The only thing for certain is the name, 'Toothless', because I love a kid's movie so/too much.
