Here's my two cents worth. In all my coils, I put the
diodes before the choke for a good reason, to protect the
diodes from the R.F. energy on the other side of the choke.  If you are
after the higher voltage "kick" provided by the counter emf developed in the
choke then it is even more important to put a diode before the choke. Some
folks call this a "de-queing" diode.
