Columbia 300 Jinx 4.5 inch Pin. I stacked my Jinx, pin and CG is about 1 inch of my Center of Grip. ( Right Hander ). This ball is for medium to dry lane conditions. it has great length and nice flip on the back. The flip is strong and controllable allowing you to read the breakpoint on medium to dry lane conditions. This ball does not like oil it squirts a little long on oil, and its a little harder to get a read on it. If you need a medium to dry lane ball this jinx or the HyJinx is the ball for you.

JINX

Coverstock: Big Flip Reactive
Core: Single Density Stair Step
OOB Finish: 2000 Degree Polish

Drilling: Pin above ring finger with the cg in the middle of the span

When i bought this ball i had no pearl balls in my bag so i chose the new JINX to fill the gap and WOW! I wanted the ball to get down the lane and not move too much or too hard and thats exactly what it does. This Teal/Blue/Silver gem gets through the heads superbly and retains its energy in the midlane. Once this ball exits the oil pattern..............LOOK OUT! The Jinx makes a smooth predictable move into the pocket. The carry that this ball delivers is insane. Say goodbye to corner pins because when this baby hits flush, they dont stand. Go a little light, messengers are flying EVERYWHERE!

Overall Impression: 9.5/10

Thanks goes out to Columbia 300 for releasing this great ball and thanks also to Patrick Birtig at AMF Moorabbin for laying out and drilling this beast.

PS: This ball is certainly no jinx on scoring

I picked up this ball used with only a few games on it.  I fully plugged the ball and resurfaced it to 1500 grit wet sand and a coat of Ebonite Factory Finish polish.  I drilled the ball with the cg directly in the center of the grip and the pin in the leverage (3 3/8" from PAP) position, 1.5" from my VAL.  No weight hole was needed.  Looking for a good all-around ball for medium to lighter oil conditions.

The first shot was a standard medium oil 38' house shot on HPL synthetics.  Some play on the lanes, but lots of oil still remaining.. backends still fairly clean.  The ball got great length and a had a very strong, but smooth backend.  All kinds of area with this ball... just swing it out anywhere right of the 10 board at the break point and it was in the pocket.  The strong roll of this ball produced excellent carry.  I think it would make an excellent league ball.  After a game or two, I was able to move inside and still had plenty of backend to hit and carry.

The second shot was a semi broke-down scorpion pattern (41' PBA) with some carry down.  On this shot, I was throwing my Fury 18 at the arrows out to around 10 at the breakpoint and in the pocket.  With the Jinyx, I was able to tighten up my line and play 14-15 at the arrows out to around 9-10 at the break point.  The ball wasn't finishing nearly as hard as on the house shot (due to the carry down..and probably playing deeper on the lane), but still had enough to carry.  If I pushed the ball out a couple too many boards at the breakpoint, there wasn't enough recovery to make it back to the pocket (but then again, not many balls have enough recovery to make it back on those shots).  The performance wasn't spectacular, but solid.  As the pattern dried up even more, I was able to move in deeper and play a little more swing.  I made it in as far as 20 at the arrows out to around 10 at the break point without any problems being able to hit the pocket.  There are probably some better choices for this condition (something with a little more pop on the backend), but this ball was definitely playable.  I see it as a great choice for typical house shots, or any other shots with clean backends.  It will fill in on other shots when your "strong" equipment is covering too many boards or burning up.  Probably not going to wow you, but a solid performer for the price range.  Does need a little dry on the backends to work best.
