Well since I've gotten back into bowling I've thrown a lot of different equipment from Big B, Columbia, Ebonite, Track, Storm, Roto Grip, Visionary, Morich, Lane 1, and Hammer.  That being said, while I found traits that I liked in almost all of those, I've settled down to just two.  My "primary" would have to be Roto Grip, whom I was hesitant to try at first because overall I felt that I didn't match up well with Storm.  However, all of my Roto Grip equipment just works well together, and gives me a certain level of confidence.  My second choice would have to be Ebonite, I know a lot of people complain about their coverstocks, but that has never been a problem for me.  I own a TNV that has well over 150 games on it that I keep clean and bathe regularly and it's still going strong, also my Gamebreaker is probably one of the most versatile pieces I've ever owned.  So with that being said I'm not opposed to trying other balls, but I just feel very comfortable and confident in Roto and Ebonite.

IMO its alot easier to build a 4 or 5 ball arsenal if you use just 1 company. They are normally very good at producing cores and covers that fit and work together very well. Lord knows I have drilled up 100's of balls the past 3 years and using different companies to me is too confusing. There is also way too much overlap as well. I also think it takes more balls to complete a multi company arsenal than just using 1 company. Thats just my 2 cents..

I have been using all RotoGrip stuff for the past 3 or so weeks and I am actually learning what condition each ball is best suited for. I also don't see any condition I cannot cover with the 6 (5 + spare ball) balls that I have drilled up..

I currently throw different companies' balls, and of the companies I've thrown(some of which I've only thrown one recent ball from), I certainly wouldn't commit to any one of them.  I have yet to throw a Morich(which I hear can be hard to control on tougher conditions), Visionary, and Storm.  I would like to be able to say that I'd commit to Storm but I have to see if I do well with their equipment.

Well I dont use just one company however after trying a few newer balls side by side with my old gold rhino pro I think I am just going to start buying pre 2000 equipment.

After many years of trying any and every brand of bowling equipment the market has to offer I realized for my game one particular manufactuer matches up the best with me.  

From that moment I decided to only use that one company.

There are only so many years you can go to league with a lot of balls contemplating what will do what and how, why, or where.

I've got stuff from most manufacturers but I like to keep most of my purchases from one manufacturer.

From 1989-1994, that was AMF. From 1995-2007, it was Storm. Now it's Lane #1.

As others have mentioned, keeping things to one manufacturer keeps it simple. You can generally tell where a new offering is going to fit based on your experiences with the old offerings.

It's hard, unless you're buying every new release, to mentally keep up with every company's reaction profile. I'm doing good these days to handle two of them, Lane #1 and Storm. I kept Storm in play because, for me, the coverstocks are so different between the two companies that Storm fits in holes that Lane #1 doesn't cover, and vice versa.

What predicated the change from Storm to Lane #1, for me, was when I changed my release and more or less rebuilt my game starting in about 2005. I needed something that rolled more and most Storm gear I've owned over the years wants to get angular. I don't need a lot of help from the ball in the backend and I started to find the Lane #1 gear to be more rolly and predictable.

I use to roll anything but now I go with brunswick.  When I got back into bowling about a year ago I bought a equation and that was fine.  The first time I saw the pba patters my ball did nothing and I have hand so I was pissed.  The next week I bought a twisted fury and a blast zone and now I haven't looked back.
