if you end up buying so many balls you are lost in what you need to throw when you are bowling. Consistently changing balls. when you are bowling good,, chances are its the same 2-4 balls you mostly use because you have built the confidence in those and learned the adjustments.
This is an interesting, and I think relevant, observation. I was exclusively Lane#1 for close to 10 years. I decided to branch out because Lane#1 dropped their PBA Registration, and just as important, they went through what I think of as a 'dark' period after leaving Brunswick for their covers.
When I did throw just Lane#1, I never had more than 6-8 balls. Overall, I felt each piece was fairly versatile over a wide range of conditions. I can't remember a Lane#1 I considered a dud. I still have many of the older Lane#1 balls I still throw. Right now, the Stealth Bomber is one of my favorite pieces among everything I own.
On the other had, when I went to the mixed company arsenal strategy, I ended up buying many more balls. Many ended up being narrow in usability, so they sat most of the time. I've found a few gems in the Columbia, Motiv and Storm lines that get a lot of continuous use, but I've had to purchase many balls to find them.
I guess the short of it is that I could probably be happy with a much smaller Lane#1 arsenal and be just as effective (or not). Each Lane#1 ball would cost significantly more, but my total net dollar outlay would be less. Maybe this is all just a psychological head trip, but at least in my case, real world empirical evidence says it's true.
