Hi Jason

"Why use anything except 100?" Example: If you have a lot of
power and a small cap you can choose to go for 200 BPS. An other
reason: The look of the streamer and the general comportment of
the coil is different at different BPS. I can give you an other
example 2 years ago I was visiting a friend living in a  farmland
 
far from any city, we decide to build a small coil, we look at
the part available and find an OBIT, enough wire to wind 10" on a
piece of 3 1/2" PVC, in the village at the TV repair shop we find
a stock of 200 .016 uF 1.2 KV mylar cap and 2 soup serving spoon
for top load we try a static gap but for experimentation we
decide to try to use a small universal motor for a asynchrone
rotary spark gap. I don't really know why but the coil work best
at 335 BPS and the safety gap fired about 7 to 10 time a minute.
After 2 years the coil is still alive and with this set up we
manage to have time to time 14" streamer. You can see a small
video of it at:

open the folder tesla and download the file cheap_coil.mpg

I think the secret of success with ARSG is A WELL ADJUST SAFETY
GAP and using a BPS superior to 120 in USA or 100 in europe.
