What I Was Looking For In This Layout: We've been hearing that Brunswick was looking to create something that was very aggressive and this was that ball. I was looking for this ball to really move on the backends for me.

What I Ended Up With In This Ball Layout: I'd have to say that this layout gave me a great look on heavy oil. I tested this ball on a modified house shot with a higher volume of oil. The Brunswick Siege really starts gripping the lane early because I left the surface at box finish.

With the combination of the new M.A.C.E. core and Solid Propel coverstock, this ball generates a ton of reaction and a very large flare around the ball. I would have to say that this ball flares nearly 7" for me.

On the heavier oiled condition that I tested the Brunswick Siege on, I stood on the 30 board and stroked the ball out to the 8 board at the breakpoint. With the box surface and strong midlane reaction, this ball had no problems at all getting back to the pocket and exploding the pins. I even left a few nine pins which isn't a bad thing with the matte surface.

To see what this ball could do, I moved right on the approach to try and play a tighter line to the pocket. This line worked well too as the ball did not seem to have any difficulty clearing the heads.

As the lanes broke down, the surface at box finish proved to be too much for me. This is going to be a great addition to my bag for heavy oil. For lighter to medium oiled shots, all you would need to do is hit the coverstock with some Brunswick Factory Finish Polish and it would react great on the backends.

I think Brunswick did a great job in creating the Siege with the new M.A.C.E. core and wrapping it with the Solid Propel coverstock. I recommend this ball to anyone in search of more hook in heavy oil.
