I have them very different. On the ones I have drilled the same, Original Rising layout, love that layout, both at 4000 abralon. The 715T for me was about 7 feet earlier with alot more midlane and strong overall ball roll and continuation throughout the lane. The 916 AT for me with this layout is alot like the Rising SE was for me. It was alot cleaner in the heads and midlane. However when it makes it contact with friction is turns without a question or doubt. The only thing is that it is not an uncontrollable flip. It is still controllable and easy to work with. However the move is strong and can really let me give away the headpin on shots.

 

I would say in overall terms of hook I have the 715T about 3-4 boards further left. It doesnt turn as hard as the 916 but it starts up alot earlier and is not able to stay in play as long unless there is alot of oil. If you are looking for heavy oil you cant go wrong with the 715T, or the 916AT but I would recomend the 715T over the 916AT. If you want the ball to be usable longer throughout the night and start further right and move in with the oil as the night goes on I would go with the 916AT over the 715T only becasue the 715T when drilled strong will force you into the oil more at the start of the night.
