they're not too far fetched

Here is my understanding.
I absolutely trust my father with my life. If he was holding me over a 10,000 foot cliff, no doubt in my mind I'll be afraid. That is not perfect Bitachon, I am not trusting entirely in him. Is that a definitive yes, or no? Absolutely not.
Recognizing that it's my father holding me in that position is emunah. To not fully understand that that's the case, is a lack in Emunah, once again there is undoubtedly a range, to what extent do you understand, or to what extent to you recognize that it's him. And the same for when you are pulled to safety, how much do you understand/recognize that it was him who saved you.
The 2 mehalchim question had to many assumptions for me to tackle.
Say you have 2 roads from point A to point B. One is flat and windy, one is bumpy and straight. Or one is perfect at the beginning, but bumpy at the end, while the other is windy at the start but straightens out in the middle. Both roads take you from where you are to where you need to be. Both roads are hard, and you can't take the easy part without the hard part. But after all is said and done you get from point A to point B. And that's where based on your assumptions God says choose your way, you have bechira, but all I need is you to be at point B.
But I disagree with the whole second part, so who cares what I think.
