Troubles. Nice warm touchy, touchy, feely post. Fortunately it seems you are blessed with superb copilots who as you say can fly better than you and you can learn from them. Have you tried flying with copilots right out of flying school now in the RH seat of a 737 with a grand total of 250 hours in their log books?
One would fervently hope that you can fly better than them. As for asking your copilots to comment freely on your CRM etc - do I detect just a teeny weeny bit of "I would like your praise to massage my ego?" Let's face it, no F/O is going to tell you to your face that you can't fly for nuts and have a complete lack of CRM. I have no doubt judging by your post that you are a first class pilot with admirable traits including CRM - but it's a bit yukky to ask your F/O if he likes your style, don't you think? That is just begging for compliments.
