Go with what feels right for you.
In my own experiments I found that at some point lots of weight in the grip doesn't add anything to the hitting experience and only adds weight that still needs to be heaved around.
Don't focus on balance is my primary advice. Focus on swingweight and static weight which will usually suggest a balance that works for you.
In other words, the right balance should be viewed as a product of a sw and static weight combo in most instances.
For example, I've found that certain swingweights provide me with a good feeling of stability and plow and certain static weights are just enough for me to absorb heavy incoming shots without being too heavy for me under pressure. Combined this sw and static weight usually results in a given balance. No matter how many times I tweak a frame, regardless of manufacturer or specific frame, I keep coming back to the specs in my signature with only minor differences.
