Brunswick Siege is a new high end ball designed to combat heavier volume oil patterns. The Siege has a asymmetric core named M.A.C.E. (Mechanical Asymmetric Core Engineering) which is a very Low RG core designed work with a new coverstock call Recoil. The M.A.C.E. core’s High differential will assist traction in higher volume patterns and the High RG asymmetric differential will allow the Siege to respond quicker to friction. Brunswick’s Recoil cover is designed to improve mid-lane and backend reaction that allows you to combat today’s oils and lane surfaces.
I smoothed the Siege down to 4000 abralon then drilled it 45x5x65 with a weight hole about one inch from the mass bias mark. On the house pattern this ball created surprising length, strong but controllable move at the break, and it went through the pins with amazing energy. I was able to use this ball for 2 out of the 3 games in league competition before it became too much ball. I then tested my Siege on the 2009 USBC pattern even though I had to play the lanes straighter the ball still gave me a really good reaction, but I wanted to see what the Siege would do if I took it back to 1000 abralon. After The quick surface adjustment the Siege really showed its teeth I had more area at the break point (a good 2 to 3 boards) with this ball than I have had with my other equipment. I found it really great that even at the 1000 abralon finish the ball still cleared the heads and maintained energy at the pins. I would have say that I have found my new favorite ball to use on high volume patterns.
