I love black headed! They are one of the most beautiful species of Parrot in my opinion.
I had one for a while and he was a complete buffoon, very very funny, and I would not worry about the size of the balls because they would destroy a football if they put their mind on it lol.
I miss his antics but he was a tiel killer plus he screamed like you can't believe it every time he wasn't the centre of attention... But he'll be your only bird so you won't have all these problems,!
I love your choice of stuff, there is a bit of everything

i still got petsmart and local pet shop gift cards plus 50 coming into my account from family for bday. so thats like another 100$ i can spend. want some rope perches, few more toy making supplies, bed, shower perch, nail clippers.

petsmart has "buy 2 get one free" for toys, at least in my area

bought this stuff today was hoping to get smaller rope perch too. but pet smart was outo f most of the bird stuff.

look wut came in mail today

I have that ladder. My cockatiels love it.
