Well, I added about 4 more turns to
my primary and with the addition of those windings, I am now
seeing streamers off the topload and I did away with the
strike rail.
I am currently at about 9 - 1/8th turns.
I am seeing about 12-15" streamers.They seem to primarily
appear on only one side. Not sure why this would
be. The other thing I noticed is I can hear faint
snaps every once in a while after I shut the coil
down. I tried to hear where they were coming from and
it sounded like "static electricity" and sounded like they
came from the secondary coil. Then I touched the
secondary and got a little bit of a shock :) I suspect
it is due to the bucket cap not having a resistor across
it.

Thanks for the help guys!

You want the RF path for the secondary to be short and
direct. Using the
slab floor is good if you're building a BIG coil that sits
on the floor.
In your case, though, the bottom of your coil is sitting a
meter off the
floor. You might try just setting the coil on the
floor (if your
cabling allows that). Careful of strikes to the other
primary components.
