Jigsaw is very popular in our league. I and another bowler use the 930t. There is no comparison between the two balls. The 930t handles more oil, covers more boards, and seems to be more controllable. The Jigsaw is good when the shot has broken down, but needs some oil up front.
930t will surprise you. Dull ball, strong cover that moves off the dry but does not burn out. I don't recall seeing any ball like it. Closest I can recall is the Cell, but the 930t retains more energy down lane when the shot is somewhat dry for a heavy oil ball.

Those that can do. Those that can't complain. Pimpin ain't easy, but it's mandatory.
Most things we like, we don't need. Most things we need, we don't like. Don't confuse your likes with your needs.
