undoubtably a safe and wise decision. more pilots could learn from your type of thinking.
The IMC would have been a help in this situation perhaps giving you more options. But at the end of the day making a good safe call means you live to fly another day.
It reminds me of a trip I went on earlier this year with a bunch of helicoptor pilots. We were due to fly to Amsterdam on the friday in March then Saturday to Bruge and Sunday home. On the friday the weather was mariginal but within my experiance and IMC rating and the heli boys were pushing to go (none of them were IR and there is no IMC for heli) so I said OK. I got as far as Stanstead who refused me a Radar Service and turned back. The heli boys went on in viz that was pure IMC at 600ft (take a look at the map for MSA). Fortunatly they all arrived safely in Hilversum that afternoon after crossing the channel dover-koksijde at 600ft apart from the guy who took his R44 through cloud (he and the A/C not rated for it!) and took photos to prove it!! (Very nice solid clouds shots in the sunshine!)
We sat it out at home and on the Saturday we had clear blue skys and nil wind so we flew over and joined them at Ostend. Result was a great night on the beer!
I don't regret at all turning back and sitting it out depsite the interesting names I was called by some of those who pushed on!!!
Don't be afraid of what others think of you, be safe!.
And before the heli boys (who I am NOT having a go at - you make your own decisons) have a go at me and say they can fly in less than fixed wing VFR viz as long as there speed is appropriate to the conditions forward viz at Stanstead was around 500m which without a RADAR service was unaccaptable to me.
