What I Was Looking For In This Ball and Layout:
This ball was drilled as 1 ball in a set of 3 for Powerhouse
Training Clinics class demonstrations.No ball reaction was intended
when this ball was drilled. The purpose of the 3 Raid balls that I
drilled was to video and demonstrate how moving mass bias location
affects your ball reaction. You'll note that all 3 Raid balls are
drilled with the exact same pin positions, but different mass bias positions.
What I Ended Up With In This Ball and Layout:
To start with, you're never going to have any problem with
the Raid in the front part of the lane.The coverstock comes from our Angular One ball, one of the most
successful balls of last year. The
veneer is very clean through the front of the lane, particularly in it's box
condition (4000 w/ Powerhouse Factory Finish).Furthermore, with the 5 1/2" pin positions that I used, there is simply no
way I was going to get any early hook from the Raid. It glides through the front of the lane
effortlessly on all conditions.
In the midlane is where I start to see some difference between these three balls. This Raid used a 75 degree layout, giving the ball the strongest downlane motion of the 3 Raid balls. I find that when this Raid senses friction, it wants to move immediately.This ball really revs quick off of the breakpoint, and makes the most
angular shape in the middle to late portion of the lane.
In the backend, this 75 degree Raid creates a lot of entry
angle through the pin deck. Devastating
pin carry and quick movement are the signatures of this Raid. For my game, I actually tend to prefer the 45
degree Raid on most average conditions, simply because it tends to make the
breakpoint a little more stable. For
bowlers with weaker hands, higher speed, or slicker lane conditions, this 75
degree layout would be perfect.
