i was at rice yesterday and today (29/15) my bud (18/18) .
silver , I disagree with you about few things :
1) 85% of the time trout bites before I even finish tightening my line so I don't think they scared/spooked , I think they very curious .
2) where is no need to hide a hook , if I use dough (I grab some of it and roll a ball and keep rolling it for a minute or so , and it last me for quite a bit , but you have to do it with dry fingers) I always leave end of hook , if you use small hooks and cover it all - 95% if will swallow it (we had to keep 3 yesterday and 2 today because of them swallow)
3)trout not carp or sturgeon

they can just take it (from my experience) . and I always hold my rod , especially after casting and slowly tightening line , if no action right away I leave it a bit bent and carefully grab it even on a small taps because if you will wait for your rod to bend hard - this means it already swallowed it

or you can have a situation when you have fish on , and it ran into a snag .. (happened yesterday to my bud , today to me ...)
4) my leader is at least 3-4 feet if I cast into a "hole"
The method you described is to "catch and keep" , I prefer to play with setting a hook on a small taps , this way fish is almost always ok after releasing it .
I agree with you on "don't fish the dock" part
