Fair enough!

I voted already. I prefer 16k/8k myself, as I'm almost sure I won't need 16ks of RAM, but I agree 16ks of RAM is more flexible to people specially if you want the most people participating. And, tho I was worried 16ks of ROM would be a bit scary and 8ks more easy to fill for newbies, I saw people was not scared with 16ks of size. So at then end I think 16k/16k will be the best for all, and voted for that.
I'll try to keep it 8ks of RAM myself as personal challenge, but only cause I want. And if finally I need more RAM, hey, I'll be happy to use it.
