I usually went with a shorter heavier stabilizer but I know guys that feel more locked in with a longer lighter weight stabilizer. The simple difference is the weight is farther out and it doesn't't have to weigh as much to give you that center balance at the bow at full draw. Some have also told me that it makes for a better follow through with the top cam or wheel falling forward. I personally use shorter heavier stabilizers. I think it has a lot to do with prefrence and your shooting style.
