David,

As Malcolm stated, Q's over 100 won't really make a noticeable
difference.  A close wound coil will generally have a Q of much
more than 100, so a close wound coil will still give excellent results.

You're getting nice performance from your coil.  And yes, getting the
longest sparks is a popular goal.
