    Ruthless - Lives up to name

    Posted by Patrick Shipley on Nov 8th 2019

    Right Handed
    Rev Rate – 380-400
    Ave Ball Speed – 15.6
    Tilt – 22.70
    The Hammer Ruthless with the Juiced coverstock lives up to its name. I have my Ruthless drill with pin up and to the right of the fingers.. My Axis Point is X=4 1/8” Y=15/16”. It is just overall strong, midland and the backend. It gets through the heads clean, but just annihilates the pins. This ball will always be in my bag and should be in yours as well. If you want a strong symmetrical ball, this one is for you.

    Great Complement To The Flawless

    Posted by Andrew Jensen on Sep 9th 2019

    It is unbelievable, the amount of motion this ball contains. It has a great complement to the earlier released Hammer Flawless, which goes everywhere with me. These two are THS (Typical House Shot) killers! The Flawless, to me, was a clean motion that picked up the middle part of the lane a bit better than most balls out there. The Ruthless however, gives you more of the same but with more earlier motion than the Flawless. I was blown away by the change of direction this ball gives. When the lanes are fresh, I will be using this ball to start. You can trust as you move left, this ball will recover from places you never thought your bowling ball could. This ball will be great for a lot of surfaces you bowl on. I believe this is a motion you can trust!

    Perfectly Flawless!

    Posted by Michael Romero on Jun 20th 2019

    The Hammer Flawless is Perfect for any bowler! Given the price point for the ball, you will get your bang for your buck! If you are looking for a ball to use during league or tournament for transition and that reads the friction (dry) really quick, look no further than the Flawless. The Juiced Pearl Coverstock allows the ball to clear the front and midlane with ease and give you a strong but predictable reaction on the backend. This is a good compliment to the Hammer Black Widow Pink as you can almost play the same line when transitioning.

    Why did I not get this ball sooner?

    Posted by Brian Wolf on Jun 12th 2019

    Out of the box myself and a couple of my league mates thought “that’s a pretty ball.” After admiring the glittery blue (with pink and white swirls) exterior of the ball it was time to see how it looks rolling down the lane. First impression after getting loose was that the ball was stronger than expected. For being a mid-performance ball it definitely had no shame acting as if it were of the high performance level. After realizing what the ball was capable of, I got lined up and the pins stood no chance. If I missed left the ball would hold and if I missed right the ball came screaming back with pin carry being absolutely unbelievable. It’s safe to say I had a flawless (no pun intended) first experience with this ball and only time will tell how it hold up. I believe Hammer has a gem on their hands and don’t let the color fool you, this ball has some attitude. It easily lives up to the saying “Look good. Feel good. Bowl good.”

    This ball really is FLAWLESS!

    I drilled mine the same as my pin-down Web Tour and they really complement each other well!

    The Flawless provides a little more length than the Web Tour but also pops more on the back. I can get as far left as I want and it still continues and doesn't back off.

    This is going to be a go-to ball later in blocks when I need a little more continuation down lane.

    good ball for older bowlers

    Posted by william cowell on Mar 5th 2019

    I am 83 years old and do not have the speed I used to. The ball goes long makes a left turn and destroys the pins. Works well on wooden lanes.

    What can I say about this ball other than WOW! From that first moment you take the ball out of the box and the Pink with the blue sparkles I knew it was going to be something special! This ball rolls as FLAWLESS as it looks! Its clean through the front part of the lane but still reads the mid lane well. This ball has definitely earned a permanent spot in my bag!

    Hammer Flawless

    Posted by Patrick Foley Jr on Jan 25th 2019

    The eye catching colors of this bowling ball are not the only thing that will catch people’s attention. This bowling ball is very clean through the fronts and shapes well of the back part of the lane. Not the strongest bowling ball in the Hammer line up which will be great for anyone bowling on a House Pattern. This bowling ball strikes with ease and mixes the pins up better than most. This bowling ball will definitely be in play for the bigger hand bowlers that need something that doesn’t jump off the friction as soon as it hits it.

    Flawless from core to cover, this is packed with new core (40watt) and wrapper with proved Juiced Pearl cover. the mix of low RG (2.520) with High Diff (.041) give this gem a great mix for mediun to dry conditions. It is super clean thru the fronts and mids and pack a strong roll on the backend.
