It doesn't matter where you start. Pick a spot. Any spot. Any spring. Any location. If it doesn't balance, start moving things around until it does. We've already stated the guild lines of what changes what in regards to rate and shock location. If you can't make them balance no matter what you do, change a spring on one end and try again. Repeat as often as necessary.
Only YOU can determine what works. This is not a thread full of answers. This is not a thread with posted setups to copy. I am dead set against those anyways. This is a thread talking about a technique that people can learn for themselves that will allow them, potentially through a whole lot of time and effort (that's the bad news), to arrive at a nice setup that works well for them.
