Welcome to the world of Balls.

I'd say the easiest and most cost efective way to start would be to get yourself a bunch of Normal females and a couple of nice double co-dom males.
Maybe a Bee or 2, Lemonblast, Pewter etc.

It also depends on your budget and what you like in the snakes you get.

I personally love anything with Pastel mixed into it. Just me though..

Good luck,
Gavin
