What I Was Looking For in this Ball and Layout:
After practicing with all of the previous balls that I had drilled, it was obvious
that I had one enormous hole in my arsenal before traveling to Las Vegas. I was
lacking a medium range, smooth breakpoint reaction that would allow me to read
lane oil, pattern, length, and overall reaction. While some of my other balls
are outstanding pieces of equipment, it's always best to find a nice smooth reaction
to help you read lane patterns.
What I Ended Up With in this Ball and Layout:
The SR300 performs just like you would expect a lower differential ball to perform
in the first 20 feet. No issues with getting the ball through the heads. The slightly
higher rg and lower differential, combined with the GB 10.7 coverstock allow this
ball to just glide through the front of the lane. This is definitely a trait that
I'm looking for in a smooth reacting bowling ball. I don't want the ball checking
early like my Infinite One or Big One would. The SR300 is a champ in this department.
Looking for that smoother reaction, I chose a little stronger pin than normal
for me (4 3/4"). I typically use pins in the 5 1/4" to 5 3/4" range to cut down
the track flare and delay reaction. But when you are looking for a smoother reaction,
you want the ball to read the lane slightly earlier and lose some of that axis
rotation. The SR300 flares approximately 3" for me in this pin position. By using
a stronger pin position than normal, I am able to get the ball to "burn" off some
of the length it builds through the first 20 feet of the lane.
I chose a 5" preferred spin axis to also create a smooth breakpoint. Notice that
this is the same layout as the Infinite One that I've reviewed. The overall shape
of the two balls is actually somewhat similar. But there are two major differences
between the balls. First, the coverstocks are radically different in aggressiveness
and preparation. While I left the Infinite One at the box condition 500 Grit Abralon,
I used a gray scotch brite pad on the SR300. I was looking for a nice smooth breakpoint,
and gray scotch brite gives me this kind of look down lane. Second, the core strength
between the two balls is much different, as the SR300 has only a .038" differential.
I knew that the ball was going to flare much less, creating less friction, which
creates less hook potential.
Due to its lower flare potential, the SR300 is simply not built to be a larger
hook potential ball. So why try to make it into that? The SR300 is a perfect benchmark
type reaction that allows the bowler to read the lane condition. Powerhouse Training
Clinics students have learned about lane play techniques and know the value of
this type of bowling ball. This is the type of reaction that can put you into
the right part of the lane condition to optimize your scoring.
***Our ball reviews are developed from a wide variety of lane conditions, surfaces,
and environments. We are attempting to give you an idea of our overall experience
and findings from a ball. Remember that all bowlers are different in regards to
ball speed, revolutions, axis rotation, and axis tilt. Bowlers will see different
qualities from bowling balls based on these factors. Be sure to also take into
account the bowler's environment (lane surface, oil pattern, etc.) and their expectation
(hook, score, etc.) before drilling a new ball for anybody.
