Which Cold Steel thrower is best for practice?

[TrailBlazer420]

Since I was a kid I have been throwing everything I cold get my hands on at trees. Everything from cheap machetes and hatches to screwdrivers and weed whacker blades, also full size axes (takes two hands). I got pretty good at throwing random things and was impressing my friends. I went and got myself a Cold Steel throwing shovel and found I was scary good with it. I want to start practicing throwing knives but I don't know what to get. There is a wide array of throwing knives that cold steel makes and I can't make up my mind. I definitely want to get a true flight but they are slightly more pricey and I want to have multiple knives for practice. Which one would make a good set for a beginner?
