Eternal Cell is a great ball for me on flatter patterns as it is great in the mid-lane. I know what you all are talking about with regards to the ball motion but I do keep surface on it and it's more of a tournament ball for me. It does excel at that and it's a valuable motion to have in the bag.
For house conditions though, it may not be the most recommended. That doesn't make it a bad ball by any means though. It a fantastic ball for what it is. For those who didn't like it, I'm not sure why exactly they were expecting a THS killer.....
