All of the above is good advise. If you are going to give line to a fish and work to get it on the reel, keep tension on the line as you let it go with the fish, keep your rod tip up to act as a shock absorber for surges or if you have knot in your line and have to stop the fish unexpectedly. I don't have great expensive reels but all have decent drag systems. I have never caught any really large trout but have a 7.5 grass carp; a couple of 5.5 largemouth and a pretty good sized channel cat on my 3 wt. because I had decent drags on the reel.
