3.5# would be the right weight to get. Not sure what the difference is between Ghost and LWD. I've used the LWD in the past by it's self in a G22 that I had and I like the let off/break of the trigger. Really that's all the Connector is going to do, adjust the let off/break, the Trigger Spring controls the pull up to let off/break along with the striker spring. Since I use CCI primers to reload with I keep my striker springs stock, need all the "umph" I can get to fire off the CCI primers.
