Nord, I like the markings on your ball. As, it allows me to follow the ball rotation down the lane. Yes, it does hit heavy, as you said. The ball rotation turns forward as it hits the breakpoint.
I am a proponent of particle covers, and have 3 in my bag today. Hard to find current balls with that technology. As, porous covers seem to be the flavor of the day.
The particle expansion is a new twist to me. My balls are diamond and carbon particles. They act more like studded snow tires. But, each ball in my bag gets good traction. Different oil volume dictates the different cover I will use. (Particle-pearl, particle-soft and particle-hard covers)
Like you, since my knee operations, ball speed has been my problem. What used to be 17.5 mph now is more in the 12.5-13 range.
I recently got my first all urethane ball. Was prompted to do so by reading your other topic. Thank you for that. The outside, straight-up line is so new and different to me.
