Im currently building a Kyosho P-40 and I need to balance her out. The manual gives a certain range, such as "the center of gravity can be anywhere from X to Y back from the leading edge". Should I balance the plane further back towards the trailing edge or closer to the leading edge? Pros and Cons? Thank you in advance for any input.

I assembled that Kyosho P-40 back in June of last year. The manual showed a range of 95-105mm. (10/25" or 2/5" range) You probably won't be able to tell the difference between a CG at the 95mm location versus the 105mm location.
I'm sorry that I seem to have lost my building notes I took when assembling that airplane, or I would have told you the geistware numbers. Mine came out to 5lb 7oz and I'm flying it with an OS50FX. I put retracts in mine. They didn't come with the airplane so I had to order them. Turns out the Kyosho retailer in the US at that time had no idea which of two retracts they had were the right one for the airplane. But they did know that one set would be for the P40 of the two sets. So I got both. Turns out one has chromed strut wire, the other unfinished wire. They both rotate opposite the way a P40 gear has to rotate in order that the wheels be outboard the struts when the airplane is parked, yet fold into the wheelwell correctly. Turns out the track is narrower because of that, but WTH, it's to be expected. It's ground handling isn't the greatest. It's a very good flyer.
