I drilled the Radical Bonus to be a bit longer and smoother as I drilled another control type ball at the same time, the Hammer Web Tour Hybrid. I didn't want them right on top of each other. Throwing them during the same session I was able to see I got just what I wanted. This ball get a further down the lane, has a smooth controllable shape with good continuation through the pins. Perfecto. Should work well in both league & tournaments.
Drilled my Zing! Pearl with a 70,4", 30 layout. I found it to be a be very smooth through the fronts and once it hit friction was very angular to the pocket. Compared to my original Zing! I would say the Pearl was actually stronger by about 5 boards on the fresh and I could stick with it longer as it did not run out of energy down lane.
