I must say I loved doing, and have enjoyed keeping and using, the IMCR. But you do have to use it - otherwise you become stale very quickly. Little things can catch you out - just failing to ident one thing can fail you (my examiner let me off with a ticking off at the last renewal because I idented the ILS but not, separately, the DME for the approach - even though it was radar monitored...).
But I like instrument flying, and I know lots of people don't. I don't get nervous OCAS in IMC without a radar service - though as it's against club rules I don't do it intentionally. (There's not much you can do when unit A dumps you off to unit B unceremoniously, and you call unit B to be told 'Negative radar contact, call again in five minutes...')
