I am new to picklocking. And when I say new, I mean new

I don't know a lot of stuff about this "art" but I am willing to learn more about it. I've red some post on the forum, and I am even more interested.
Now it's the time to build the tools. I don't think I'll have any trouble with the tension wrench (I think its called like that ><) but I really don't know wich "lockpick" to choose.
I am gonna use this template to build my tool : profile.php?mode=activate&u=49924&act_key=ca059a42f95d1 , but I don't know wich one to choose, and since I only have 3 piece of hacksaw, I want to build those you use the most.
So here my question wich of these lock pick you use the most and are more "universal"? Please don't tell me the name of it (like diamond or camel or wathever) because it does'nt really tell me wich one it is. Let say that the top one is the number one and the bottom one the 17th.
Thanks a lot and sorry for my bad english, I am french
