I did wonder about the decision to return IFR yesterday but the cloud base was <2000 and there were plenty of gaps, plus the cloud base at home was 1200ft and deteriorating (we actually broke out at 600ft on approach) so I'd have had to go IFR at some point. I suppose I could have gone VFR and routed west of Lasham but I'm not sure that would have been safer - at 4000 I was at least likely to be higher than the gliders as far as I could work out.
