Here's some info on the Sultan Bonsai Method from the MNS Forums,
I know there can be many different criteria for selecting males,but I thought this was an excellent post and helps to simplify things.
Selecting Males
Of course, the main thing you select a male for is by its genes. So before you even plant the seeds you know which strain, or seed stock you are going to select your male from.
When you select males from among that preselected stock, you are primarily looking for 3 features, and it is not arbitrary crap you read about somewhere, like stem thickness. It is something you can measure and record. Here they are in order of importance:
1) High Factor: You want it to be stony, however you like it. With the male you can't be too choosy because you will be smoking leaf. You will test it for stoniness, by finding small veg leaves, 1 ½ inch diameter leaves, and dry them out. Make sure that the leaf samples to be tested are the exact same size(leaf stoniness varys according to size of leaf). Then first thing in the morning right when you wake up, wake and bake. Take 2 dried leaves pack them in a bong first thing in the morning right when you wake up, and take the single biggest hit you can and hold, and hold it for as long as possible, exhale, wait a few minutes and then rate on a scale from 1 to 10. Only one bong hit per test, and only test one sample each day, right when you wake up. Do this a couple times with each sample, if you have time. You will be surprised what a variation you will find, and if you smoke right when you wake up and you have a superior strain, you will also be surprised by how high you will get. Note: if you can finish the bong then you need to use more leaves. there should be enough material in the bong that you can't finish all of it.
2)Vigor and Form: This is just like a female. You know that plant, the one you are just praying will be a female? Well when it turns out to be a male, you select that one, provided the leaf is good and stony.
3) Length of budding cycle: Usually, the earlier flowering males are more desirous, because generally people prefer a shorter budding cycle.
These are the three factors that can easily be isolated and measured, and these are the only three factors that you consider when selecting males for the bonsai sultan method. Keep it KISS simple and you are bound to come up with a winner
