Got a chance to test the Crux hole on a Brunswick Evil Siege. Wasn't able to get before and after footage as I had hoped due to limited proshop hours. However the results so far have been good.

The Evil Siege wasn't a great ball for me. It was an okay ball at best. Tried some surface adjustments but just not anything that stood out. After testing the Crux hole on this ball I was impressed with the increased down lane reaction the ball had. It was what I originally expected when drilling the Evil Siege has a compliment to the Siege.

I have some more balls with low games that I would like to test as well over the summer. The goal is for before and after footage on the same lane in real time. Not shooting before footage driving home and coming back to shoot after footage.

For the first step in this process I am pleased. Hopefully more test will yield similar or greater results.

Yes the motion hole would work as well. Motion hole has flare problems to watch out for.

This Crux hole increases the ball dynamics when on the center span as much as a p3 hole from all the results I've seen using the blueprint software. It does have a bigger effect on the int. diff then a p3 hole.

When the hole is lowered closer to the the thumb the effects are as strong as a p4 hole at that point. Because like a p4 hole it is near the thumb and is taking a large chunk out of the core. It still has a bigger effect on the int. diff. and diff in many cases more then a p4 hole.

When I first posted about this on bowlingchat it was prior to the release info from Mo on the Motion hole. It was mentioned to me by another member on there who was assisting Im guessing with the Motion hole data. I can across this by accident when testing x-hole locations to fine tune some layouts I consistently use.

It is just another option that can be had for adding a weight hole to a bowlingball when your limited on option because of a shorter pin. Taking weight from the center of the span or an inch down doesn't shift much weight because of how close it is to the center of your span.


The hole on the center of the span can be felt when holding the bowling ball. When you move the hole down the hole can no longer be felt.

It is my first time out bowling in 4 weeks and appears my foot is a little further left then it should from my body on a few shots causing me to hop to catch balance. This was shot during my first game of bowling about 4 frames in. The Strike King video that is going to follow gets better after warming up. Looks like rust and timing a little off in the beginning.  With me not bowling this time of year there will be issues to work on before league starts back. I hope playing lots of golf will help.

After having watched the video, this is something I have seen before years ago.  I remember a driller here in my area that had a Timberwolf with the same weight hole.  When I asked him what the deal was, he said it was to get top weight out and add "bottom weight" which will help the ball get around the corner better.  The irony, was that he was the only person I ever saw with a weight hole in the center of his grip.

Ive never seen it used before but I wouldn't be surprised when it comes to x-hole locations. Especially if you had a ball with excess top weight like an x-out with 5 ozs top weight.

It wasn't till the bp software they you can see the effects it has when taken out of the side of the ball. (pin even or above the fingers) Pin down drilling it increases the int diff still but not as much of an effect on the diff.

Do you remember which ball or tournament? Would be worth seeing.

J_Mac beat me to the punch.  Tournament was the 2002 Cambridge Credit Classic.  Doug actually finished 3rd.

Very cool. If the pin is below the fingers the crux hole increases the int diff but lowers the diff. I can't tell where the pin or mb is on the TPC is but im on my phone which doesn't help. The hole appears to be less then an inch in diameter.

I can say for sure that when the pin is even or above the fingers the Crux hole will be taking out a lot of core from almost any bowling just like the thumb hole.

I will see if I can find anything further watching it from home.
