There is still a difference.  The difference is not the appearance, but 
where the sparks tend to stay.  When i was running my VTTC recently, the 
24" sparks (without a target to spark to), stayed in the exact same 
place!  The SSTC in that pictures is very straight looking, but also notice 
how they waver around quite a bit.  I would guess those sparks are about 
16" or so, and they move around several inches when you compare where they 
end (the tips of the sparks).  With my tube coil, the sparks were 24" and 
the ends were in nearly the exact same spot everytime (much more stable 
than the pictures in my website show!).  But i guess Stephen is right, they 
are very similar.
