Less labor involved in making them.

IMO the reactive coverstocks in todays balls are sponges therefore the larger the sponge the more oil it can soak up before becoming saturated. The "filler" won't soak up the oil. Coverstock is also the more expensive material in the ball so thin coverstock balls are cheaper to produce from a material cost.

I have had at least five balls crack a long way or the whole way around the ball. All have been thinner coverstock balls with the filler material. I have never had a true two piece ball crack in that way.

I have had true two-piece balls crack, although not completely around the ball like a ball with filler does.

Thank you for all your replies.

The reason I asked this question was that the Lane #1 staff once told me that they are using more expensive filler for their bowling balls. I don't know if they is such thing.

My experience with two piece bowling ball... I too feel that carry is better overall.
I didn't think about the light hit though.

Just one more question... does pin out drilling gets better carry since it hooks more at backend?

The drilling that YOU can get flush to the pocket and drive through the pins to exit the deck between the 8 and 9 pins gets better carry. Pin in, pin out, Rico, doesn't matter what the drilling is as much as what YOU can do with it.

Urethane and filler are what they are...no such thing as more expensive
Layouts create flare....the bowler creates motion

I can't comment on who uses more expensive materials on/in bowling balls. But, I do know from 10 years experience, that a Lane 1 core will dull a bit. They seem "harder" or more "dense" compared to some of the cupcake cores and fillers I see from other companies (not all). I love the oversized Diamond core, but man them things will do a number on your bits over time.

Question is does Lane1 make the core? Since every aspect of any ball is made by other manufactures depending on who will deal with the company. I would imagine the core is made by that same manufacture that is pouring the balls at the time.

You cover most of the industry with who has made their product at one point in time and the only thing proprietary maybe the core design not any of the materials.

Which is why I'm not claiming to know anything the materials or their cost. I am just stating my experience in the last 10 years, which has been mainly 900G pours.
