Yes, if you already have a license to v1, definitely start using the v2 beta - you're missing out on so many wonderful new features if you're not!
Also don't forget to use the array tools - it might be easier to select a single sphere and then using the array tools, specify how many copies you want and then set your direction.
I've never used it but I believe there's a grid array function also?
Enjoy!
