Those balls aren't any weaker than the 715A, and I'd be surprised if the 3.5 wasn't significantly stronger. The suggestions made are probably good, you could look at the Dark Star. That ball seems incredibly smooth for a pearl, and it's not a hook monster. A Mars is a little weaker but will probably require a smooth rolling layout to control it more. Same for the avalanche Pearl g/b.
Keep in mind the conditions greatly affect where you play the lane. If you're not anywhere near 10 board with your Kinetic you probably won't get anything but urethane to work out there.
