Much more likely to get a handover if flying "IFR".
Flying under Radar Information should be used in IMCR training - not that it makes much difference to the probability of hitting something in IMC because so many people fly with no transponder, with Mode A only, or with it deliberately turned off, so e.g. if VMC on top one gets all these warnings about traffic ahead but one can't see any of them because they are down below.
Fortunately it appears that very few of the no-transponder planes venture into IMC...
Unfortunately, IMV, the IMCR is often taught by clowns who should stick to their C150 on sunny days.
