You said, "I noticed that the #8 shot like a rocket with no false casts. I could feel the #8 loading the rod which I personally like but on false casting the rod could not hold up as much line as the #7."
Sounds like you like the feel of the #8 on the rod. What is your criteria for goodness in the type of fishing you are planning to do with this rod? Which line are you able to cast farthest with? If you are going to be using big flies, the heavier the line the better. And, when you are false casting, you are not fishing... Put the fly in/on the water....
