I have only owned 2 pearl Cobalt Bombs and the Liberator.
The Liberator is a condition specific ball because it's urethane but has a high end core. On the correct pattern it allows me to play areas of the lane that reactive won't allow me to play. Plus the ball is at a decent price point. I picked it up for 200 drilled.
The Pearl Cobalt Bombs were obviously more money than the Liberator but were awesome bowling balls. I really liked the Pearl Cobalt Bomb.
I thought both the Pearl Cobalt Bomb and Liberator were worth the money I paid for them. Are they more special than say my Blue Vibe and or No Mercy? No.
I think it all depends on what your willing to pay for a ball. If money is tight and your looking to get the best bang for the buck, then the Blue Vibe is THE best ball on the market in my opinion. However, if your looking for a high end ball then Lane 1 is right up there with the rest.
If you really look, the Lane 1 equipment is really not anymore money than the other high end equipment being sold from the other ball makers. It's all in what your looking for out of a particular piece of equipment.
Now for me if a bowling ball doesn't pay for itself (big money league, pot games, tourney's ect...)then it's not a good piece!
