Keith, An 8-pole filter should have more ringing than a 5-pole filter of the same bandwidth and ripple. That's because the loaded Q of each pole (crystal) is higher (bandwidth of each pole is narrower). You can think of it as each crystal covering 1/8 of the bandwidth rather than 1/5, although that's an oversimplification.
