Guys, let me tell you what, This ball is BAD A!!. I have bowled 2 league nights with it and man, 776 and 790. I have a Cell and have bowled with it for about 6 months but this ball is IT, especially on a house shot. With my Cell I had a little over/under on a house shot but the Grand Illusion has none. I have had about 4 boards both nights, had a 290 and a 279 (stone 8, solid 10) or I would have had a couple perfecto's in the bag with it. I tell ya what, this ball is the shiz on a house shot, don't miss out!
