Strong Benchmark ball from Hammer
By: Michael Thompson on March 05, 2018

BALL LAYOUT USED: 80 x 5 x 60 After loving the original Phobia from last year, I was super excited to drill the Fierce Phobia which is drilled similar to my original Phobia. With the stronger Semtex Hybrid coverstock, the Fierce gets into a roll earlier, yet still offers the same strong downlane motion needed to turn the corner when moving left. I am able to use this ball more on fresh lane patterns and yet still move in as the pattern breaks down a little bit. For me the Fierce Phobia is my medium-heavier lane pattern ball that will be 1st out of my bag on various lane patterns that I bowl on in tournaments. The Fierce Phobia is about 4-5 boards stronger overall than the Diesel and stores up more energy down the lane. This ball will be a great addition to my styles of bowlers I really like what I see in this new release from Hammer and I think this ball will be a must have ball for those that are looking for something that offers a great motion to have a strong rolling symmetrical ball in your bag. - it really continues through the pin deck! Very versatile ball… You will be impressed! With the standard 3 year warrantee that Hammer provides for their balls, this is another added value for your money!

Fierce Phobia
By: Chris Monroy on February 14, 2018

Here is my take on the new Fierce Phobia by Hammer. This is the second release in the Phobia line. Box finish is 2000 Abralon.The core is the same symmetrical core used in the original Phobia and the cover is Semtex Hybrid. The Fierce Phobia, like all Hammer releases, has an industry leading 3 year warranty and comes in a blue/black and red swirl.. My specs are that I have a 405 rev rate, PAP is 5 9/16 over and 1/8 up. I have used this ball at box surface, 4000 Abralon and polished with Factory Finish Polish. The layout I used was 55 x 5 ¼ x 70 with a weight hole. (I have an original Phobia with the same layout). I have used this ball on a variety of THS and a modified USBC White. The new Fierce Phobia is a strong symmetrical piece of equipment best suited for medium to higher volumes of oil. At box surface, the Fierce Phobia picks up the midlane aggressively and continues through the back part of the lane. The best comparison I note was when I polished the Fierce Phobia and was able to compare it to an original Phobia with the same layout. On the same shot with the same polished surface, I saw similar length. However, the new Fierce Phobia shows a stronger response off of the spot compared to the original Phobia. If you liked the original Phobia for medium to lighter volumes, you will like the Fierce Phobia for higher volumes or when you need a little more recovery than an original Phobia. I found the Phobia core to be “driller friendly” and should suit many different styles. See your proshop for the latest on the Fierce Phobia by Hammer.
