Got my Ego to replace my Arc, and boy did it ever!
i have a 15# ball, got it drilled to hook early, (pin is down and to the left of my ring finger, not sure of specific drilling)
I bowl on four leagues in three houses so I knew I would give this thing a test really quick.
House 1: 40 foot flood on synthetics
House 2: normal wall on wood
House 3: Early league: normal wall, broken down some from previous league
Late league: the leftovers LOL
House 1: on the flood i found that the Ego had the worst performance, simply because of the huge amounts of oil on it. Its basically a point-and-click and hope for the best condition. (2 out of 10)
House 2: Better option here. I found that I have more versatility playing in and out with this condition, scores have been pretty good when i used the Ego here, and i can even make 7s by flattening it out! (8 out of 10)
House 3: The early league is fun, the reaction coming back from 8 and out is great, many honor scores have been rolled in this house already by lefties and righties, I already have shot a 720 with the Ego in the month or so since i bought the ball. This ball works best for me so far on these conditions (9 out of 10)
Overall: a very good ball, good hitting and carry power, excellent for playing outside or deeper inside, versatile ball.
