Sonic Normal Thread

Use this thread to discuss the Sonic (note, Sonic Reverse has a
different thread. I didn't feel that the harmonic needed a thread, but
feel free to make one if needed).

Brief Description: The pen is
held in a slot (if un-noted it is assumed to be 23) and a conical
"charge" rotation is used to make the pen jump up to the above slot (by
default 12). The charge motion may be generated with or without the use
of the thumbflap. Newer PSers usually use the flap, but it is very hard
to link in combo's like this and therefore they quickly begin to just
initiate it with a charge motion (Note for more info please see the Charge
thread). After the push the middle finger (in sonic 23-12) is bent down
so as to allow the pen to rotate up to 12, and then unbent for the
catch in 12.

More advice:
Sonic ia another simple and easy trick that can be learned fairly quickly. It can be done between any fingers that will make it "jump" to the next pair. For example, if the pen starts in 2 3, it will "jump" to 1 2. Or the pen could start at 3 4 and "jump" to 2 3. If this is the first time you are learning this trick, i would recomend doing it between fingers 2 and 3.
This trick can be done with or without the thumbflap. When doing sonic between fingers 2 and 3, remember to charge like motion and keep finger 1 open for the pen to land in, and bend finger 2 towards you so that the trick can be done.
Tips:
-begin in 23 and catch in 12
-don't apply too much force(unless it works for you)
-make sure tip of pen can leave the thumbflap
-PRACTICE!
