I throw BOTH Storm and Brunswick almost exclusively. I average 223 between 3 leagues (2 scratch and 1 handicapped). In the past 12 months I have a 300/800 with Storm (Super Charge) and a 300 with Brunswick (Ambush). I also won an ABT Masters Title last Spring throwing Storm equipment. Just recently (past 3 months) I invested in some Brunswick equipment based on my experiemce with a used Danger Zone (can't say enough good things about that ball. Threw 6-700's in a row and 9 of 11) AND JUST ORDERED A STORM PYRO ON THURSDAY.
Personally, I find that these two companies equipment complement each other quite well. They fill in the niches where one or the other company hasn't quite got it right yet. As a random example: when my Vapor Zone is overreacting I pull out the Super Charge (have it drilled for an aggressive but arcing midlane move), when the SC starts coming up early then it's either the Rampage, Ambush or Atomic Charge.
Here's my Brunswick inventory:
Strike Zone
Danger Zone x2 (one leverage--one pin above ring)
Vapor Zone x2 (one pin up--one pin down)
Rampage x 2
Ambush x 2 (one oob--one dulled w/green SB)
Smokin' Inferno
Impulse Zone
Strike Zone (green pin)
Strike Zone (Red Pin)
Nemesis
Shock Zone
Intense Inferno (retired)
Raging Inferno (retired)
Blazing Inferno (retired)
Yes, this is severe overkill and it drives me nuts when I have to pick out what to take to tournaments. I'm a ball junkie...what else can i say...LOL.

My Storm stuff is too numerous to mention. You name I got it up to when the Fire and Paradigm series came out.
I was wondering also if the Pyro might mimic the Ambush, but from what I glean on the boards it has a much more aggressive move in the back end.
My point is: both The Big "B" and Storm are great ball manufacturers. For me, I match up well with both of them. It's unfair to bash Storm just because: 1) You've never thrown their stuff, or, 2) You didn't match up well with it.
These companies invest mucho $$$$ in R&D. They both know what they're doing. Brunswick has had their share of duds as has Storm and lets not even mention Columbia's EPX. But overall, there are very, very few Storm balls that I threw that I didn't like...same for the Big "B". In fact, the technology is so good now that every major manufacturer makes great stuff.
Just my two cents.
