Suppose I bring the two guitar strings into contact so that they cross each other at a single point. At that point energy is transferred from the vibrating string to the stationary string and the latter begins to vibrate. Thus an observable event may be deemed to have taken place: the observable transfer of energy at the particular location where the guitar strings touched. But before they touched, the energy of the wave on the first guitar string was diffused at all locations along that string and was unobserved. Would this be a good analogy for the double slits experiment as follows: the point of transfer of energy between the two guitar strings represents the materialisation of a photon at one or other of the double slits. An observable event takes place. But when the photon isn't observed at one or other of the two slits, its unobserved energy remains diffused across a wave front that incorporates all possible routes between the source and the screen: in the same way that the energy in the guitar string remains diffused along its length until the moment it touches the other string, whereupon the energy in the wave becomes manifest as an observable event. Thus instead of reverting to the notion of the wave becoming a particle, can't we view this as an observable energy transfer event analogous to the transfer of vibration energy between guitar strings?
