Should the IMCR be ditched in the quest for a greater prize?
Is there any evidence that this trade is on offer? But in the hypothetical situation that it were, just count how many IMCR pilots there are and how many PPL/IR pilots. On the basis of the number of pilots that might benefit, I reckon IMCR wins hands-down.
But as I say, I think this is hypothetical. Let's go for preserving IMCR and getting a more accessible PPL/IR. Let's not argue about which we want: we want both.
