I didn't like it (or the thought of it) light either. After a year or so hitting with my PBkai/Ignite shaft, and regularly telling people who suggested to remove it that "I don't mess with cues, I work on my action"
It wasn't that I hit them poorly. WPA/MR 9ball, 8ball, 10ball. All solid. I am actually thinking at this point that playing with the weight in was a useful muscle memory training. I was able to hit the 26/27mph mark previously with weight in, and I will measure max speed later out of interest (as I rarely break full tilt in any format).
My friend took it out while I went to get a coffee yesterday as a joke. I came back and was blasting racks of WPA 9ball. made 6balls on the break twice. Was also nice nostalgic feeling for me, reminded me of when me and my friends would turn each others trucks the opposite way round when leaving skateboards unattended at my local skate store growing up haha
