I have P78 and have tried many times without any luck at all and just couldn’t figure it out as far as effects on myself or others. This and P114 I haven’t figured out and I really want to since there isn’t much on them and this may be why there isn’t much info on them I don’t know.
I found with IS if I use P74 or P96 it stops the crash effect for me or if I over power the IS a little with one of those I don’t get the crash.
I am glad to see you around and hope all is well.
