Heh, if your GM does not like edge, then it should be removed from the game. My GMs not only allow edge to be used, but reward good RP with renewal of edge throughout the session.
Plus edge is replenished at the start of a "mission", or when GM says "all full" so to speak.
I mentioned it before, but I guess it was missed...
Do you plan on having Wired Reflexes? Only one initiative pass is... well, not normally done.
