I have a current IMC, and will be renewing it in Jan. I do not enjoy flying when the weather is poor, and therefore choose not to. In the last 2 years (since I have had my IMC) I have flown in true IMC conditions only 3 or 4 times, but I use the nav and radio skills learnt in it every time I fly. I realise that it is NOT an IR, so don't set off flying when I will have to fly in cloud. One huge danger with it is that instrument skills degrade rapidly when not used, and so need to be practiced regularly - not just used when we unexpectedly find ourselves surrounded by bad weather.
