- Weight Block: Paragon Core (14-16 pounds)
- Ball Color: Red/Black/Electric Blue All colors do vary somewhat from the picture shown.
- Ball Finish: 1500-grit Polished
- RG Differential: 16#-.052, 15#-.054, 14#-.053
- RG Average: 16#-2.49, 15#-2.49, 14#-2.52
- Flare Potential: 7" Plus (High)
- Recommended Lane Conditions: Medium/Heavy Oil
- A few tiny pit holes in the cover stock of the ball are normal
- Description: Featuring the same technological advancement found in the Defiant, the unique elliptical shape of the Paragon core defines predictability of axis migration and allows you to perfectly match up your ball reaction to the condition at hand.
The MicroBite pearl reactive coverstock uses extremely small structured additives to help smooth the transitions while maintaining entry angle at the pocket. This helps you create better pin action while reducing oil sensitivity that can send your ball through the break point.
The new Defiant Edge is the ideal complement to the original Defiant, providing the perfect combination of skid-hook-roll even on medium-heavy oil. Be sure to keep your original Defiant on hand for those heavy oil situations.

Roto Grip Defiant Edge #1      serial#12REGE30J051      
layout: 50x4x35
Ball was drilled to be used on house patterns that use HPL and SPL and be a benchmark ball to replace my Infinite Theory. Tested on 2 house patterns with HPL and SPL surfaces, and also on Autobahn and Winding Road on the HPL surface.
Found that on the house pattern, I had to look about 2-3 inches further down the lane, but was still able to play the same lines to the pocket. Did also notice on the sport patterns, I needed to look much further down lane so it would not over react. The overall performance was stronger than the Infinite I have with the same layout and sharper angle into the pocket then any hybrid pearl and reactive pearl I ever had.

Hand: Left
Ball Speed: 16-17mph
Ball Weight: 15lbs
PAP: 5 left 7/16 up
Degrees of Tilt: 17
Layout: 5 x 4 ½ x 2

The Defiant Edge is drilled pin above fingers and Preferred Spin Axis (mass bias) about 1 inch away from the thumb. The Defiant Edge has a similar roll to the original Defiant meaning real controllable and a lot of different kind of style of bowlers can use it. When you are using the Defiant for 1 or 2 games and you start seeing the Defiant not finishing you can go to the Defiant Edge and gets through the heads much cleaner and has a strong back end motion. It doesn’t have that sharp back end angle that you see in a lot of other pearl cover stocks, it is a little smoother which gives me more control during transition. I went to Las Vegas for a megabucks tournament and the pattern was a 36 foot pattern with a big volume of oil in the heads and the Defiant Edge gave me the best look when usually strong balls tend to be too much down lane when this ball kept me in play and was not flying off the back ends like other balls in its category usually does. I was able play in my comfort zone from the start and just ball down from there. If you have a Defiant you will like the Defiant Edge.

COMMENTS

Likes: A benchmark ball perfect for medium to medium heavy lanes. Also good when you want to get deeper on the lane and don't want to play a lot of dry. It reads the midlane nicely, reacts and saves a lot of energy for such a strong ball. Its also a very nice looking ball and hits good. I've had quite a few airborne messengers with this piece.

Dislikes:A little too strong for drier lanes as expected unless you have exceptional ball speed.

Defiant Edge  55 x 5.25 x 60

The Defiant Edge is the Pearl Version of the original Defiant.  The Edge does what it was intended to do, cleaner through the fronts and more reaction on the backend.
So when you start to see the Defiant start to labor or flat 10 down lane, don’t hesitant going to the Defiant Edge.  I’ve bowled with the Edge in our Kegel Summer league and I was very impressed as I was able to use the Edge on most of the patterns, which is pretty good for an asymmetrical ball.  I normally can’t use a strong Asymmetrical ball as they don’t make up with my roll and axis tilt.  The Edge gave me what I was missing , a strong rolling pearl with control.  A very good 1-2 punch from Roto Grip.



PAP 4 up 1 -1/4

Upon getting this ball, I was first very impressed at the color scheme of the ball. It is unreal how much shelf appeal has an effect with consumers and the choice of colors on the Defiant Edge gives it a clean, sharp look. At first, I was very unsure on how I wanted the ball to perform for me. I talked with Chris Schlemer and he suggested that I put the pin directly over the bridge, and the mass bias 2” away from the thumb. I have a higher rev rate, but also a high axis point as I’m stay behind the ball a lot. This layout was used to provide me with a stronger motion in the backend, as at the time I was missing a ball that would clear the front of the lanes easily, and still retain its energy in the back part of the lane. This is the exact reaction I see out of the Defiant Edge.  As I compared it to the original Defiant, the difference in the balls was obvious. Where our pro shop is located, the bowling alley has fewer units in the front parts of the lane. This makes it virtually impossible for me to throw the Defiant, as the core/cover combo reads the front part of the lane and burns out. The Defiant Edge works perfectly in this situation for me. The ball clears the lower volume in the heads here, and retains its energy, making a strong motion in the back part of the lanes. This is a very strong pearl ball, and for me, is best used when there is lower volume in the front parts of the lanes or in transition as lanes break down.

The Defiant Edge with its peralized coverstock is a nice companion ball to the Defiant.  I like this ball for the 39-foot house pattern I play on in league.  I find with the pearl cover this ball goes 2-3 feet long through the heads then make a stronger more dramatic angle to the pocket.  Having this extra continuous hooking power and motion on the back end allows me to play 4-5 boards deeper and open up the area.  The Defiant Edge still had a nice predictable motion down the lane.  In league play I am averaging 216 with this ball.  The 1500 polished finish gives me the skid flip motion that I like on a house shot..
To achieve this reaction, I had my ball drilled with the pin below the fingers with the mass bias in the strong position.  I added a weight hole as well.
As the night goes on and the Defiant begins to become more aggressive, I can move in and go deeper or switch to the Shooting Star.
For a speed dominate low rev player, this is a nice one to have in your arsenal and another great ball from Roto Grip and.
