I would like to here some opinions on brand choices? Do you stick with one company / brand or do you use any brand? I know staffers have to use only the brand they signed with, but I am not a staffer an I choose to use ROTO GRIP. My reason is easy, I do match up well with their equipment. I like the way it rolls and hits. so I am sticking with them. I don't feel that I am missing out on other company's equipment because I am confident that the choices I am making are the best for me at this time, so why experiment? whats your take?

I'm not brand specific.  I choose certain balls to fulfill my arsenal. 

I do it because I like to know where certain pieces fit. I can ball up and down with more confidence that way. Every company has a complete arsenal, so you can't go wrong with doing it.

This is just me but I am NOT brand loyal.  If I were on payroll I would be.

I tend to break my arsenal down to 5 total balls (including a plastic)

1)  Something Strong (usually put a 1000 - 2000 surface on it)
2)  Something Medium to Strong (usually with a little surface but not too much)
3)  Something Medium to Mild (Usually with some grit underneath but a shine on it)
4)  Something REALLY weak (Shiny)
5)  Plastic for spares

Current lineup is:

Pursuit-S @ fresh 2000
Innovate @ fresh 2000 + used 2000
Victory Road @ 2000 + Snake Oil
MoJave w/big shine on it

I'm probably going to add an IQ tour pearl @ a fresh 1000 with polish just to fill it out a bit.

For each spot I try and find a ball that gets good reviews by a wide spectrum of bowlers.  I've not found it exceptionally difficult to have a nice "ball down" progression over the years by throwing various brands.....

Usually if I cannot find it with the 4 balls I'll have on me, i'm probably not going to and i'm likely throwing it awful.

For tournaments where I know the pattern (maybe one extreme or the other) or PBAX, I can rotate a piece or two off the rack at home.

I'm not bringing my MoJave to bowl on shark     

Brunswick, Storm and a dash o Ebonite

Track has worked best for me. I'm not deliberately loyal, but I always end up with a Track piece. I also buy a lot used from a friend who is a ball whore. We have the same span so I get to try all kinds of stuff haha. I have 4 Track balls and a Roto Grip Mars. Everything I've thrown from Roto is great in my hands, but price is a big factor in why I buy things. Used Track ball already drilled for my span, or a brand new Roto Grip for 3X the price?

I am for 99% of what I use because of how well the equipment has worked for me. I still try other things when it catches my eye and usually end up with mixed reviews.

I think the benefit of it is matching desired reactions from high performance down to create an arsenal. When you mix and match manufactures that can be a little harder. There are a lot of great companies to choose from.

I've recently dabbled in Seismic, as Hammer's skid/flip strength has gotten to be too much for my style. Matched up well so far, so am probably going all Seismic.
