Experimenting w/ Hybrid Dirty Bomb
« on: May 26, 2005, 09:09:49 AM »
In a previous thread there was a discussion about problems some people are having with their Hybrid Dirty Bombs.  I am one of those people.

To make a long story short, I was experiencing too much skid with the HDB, and couldn't see any signs of burning up, so I figured the coverstock finish was the main problem.  After some advice from Doug Sterner and others, I decided to try taking the cover down to remove the polish and dull the ball up to see if that would solve my problem.

Answer: NO!  Just to experiment, I took the cover down to 220 and went and threw a couple of lines with it.  I think I might have seen about 3 more boards of total hook.  I also still could see no signs of the ball burning up, as I could still see some side roll on the ball as it hit the pocket (looked like it was STILL skidding!).

I threw my Solid Uranium, Dirty Bomb, Pearl Uranium, and even a Cherry Bomb on the same lanes that day.  I would say the HDB had almost an identical reaction to my Cherry Bomb, which skids the farthest of all of these balls, then makes a mild (4-5 boards) move to the pocket.  Remember, my speed is higher than average.  I could easily swing the Dirty and the Solid way out from inside and bring them all the way back to the pocket, but the HDB and Cherry Bomb were down and in (straight up 7).

Does any of this sound right to you guys?  I didn't have time to bring the surface back up, so it is still at 220 grit.  This ball still has less than 10 games on it and I still can't use it!

Here is my main question: I have heard a discussion about balls that OVER flare... is this a possibility here?  I don't understand the concept of over-flaring well enough to make that determination; can someone help me understand this?  I am thinking my last resort is to plug and put a weaker drill on this ball.  Here is a pic of the current layout:

My proshop guy (who has about 50 years of experience, BTW) just said, "Well remember not to use that layout again..."  Haha!  The guy is brilliant but can't communicate or teach very well.  He knows his stuff, but he couldn't explain anything in such a way that a novice like me could understand, unless I had spent a ton of time on this forum educating myself first.  Someone help me out here.

You're situation is puzzling to me. My HDB rolls early and is very aggressive, but my drill pattern is different (pin below ring, cg kicked a little to the right). I would expect the pattern in your picture to skid a little further, but not as much as you described.

Regardless, a 220 grit surface is not the answer. I'd redrill with the pin below the ring and the cg kicked out just a bit. Also, be sure to bring the cover up to about 600 grit again. You should be fine at that point.

Steven, thanks for your reply.  One question: if I tried the layout you suggested, would I have to be concerned about tracking over any of the holes due to the fact that I track fairly high?  I would describe my normal track as 1" from middle finger and almost touching the thumbhole the way the ball is presently laid out.

Sawfreak: With the pin below the ring finger, clipping the thumb hole is a valid concern if you track high.

I have both Dirty Bombs, and I find this particular core real touchy to drill pattern. On my regular DB, I have the pin above ring, and the ball is a real skid/flip monster -- almost too much over/under.

My feeling is that this core works best when revved early and allowed to get into a good strong roll. That's best accomplished with a pin below ring drill, especially if you have greater than average speed. Talk to your driller and jointly decide if based on your style you can move the pin down.

I agree with Steven about re-drilling the ball with the pin below the ring and the CG kicked out a bit further. You shouldn't have a problem with the ball flaring over the thumb or middle finger.

200 grit is also not the answer. Bring it up to 600 grit at the very least.

I would also use an extra hole to adjust the ending weights. Don't use much side, finger or top. Maybe bring the ball back to 0,0,0. Side, finger and top only make the ball go longer before hooking. =:^D

Is there a weight hole in that BadBoy? I don't see one.  Before total plug/redrill I suggest the use of a weight hole the ball will have to read earlier then.  Granted I have slower than normal ball speed but my Hybrid acts nothing like my old cherry bomb did, not even like my black cherry bomb.

No weight hole.  I have considered that as the possible next option before I do a complete plug and redrill.  Wayne, I probably can't go below the fingers because of my high track.  If what you say is true, me and this ball probably don't match up very well and I'll have to stick with my other stuff.
