Good question, with using a small arbour reel it's next to impossible to keep up with any trout swimming to the boat so the strip in method is used to keep tension on the line, no tension= no fish. There are so many ways to get a fish in.
Use your rod to keep the tension, small arbour reels if used and used to reel in one has to decide when to strip in and when to reel in, tension must be on the reel when reeling in, fish or not.
So you get a hit, the fish takes line out and your unable to stop it, only using your rod and palming the reel to slow it down, it stops, heads toward you, the small arbour can't keep up, this is when you start to strip the line in without stepping on it or getting it in your shoe laces

.
A few years ago I switched to the large arbour reel, it's used for the trout that swim fast to the water craft or shoreline your at. One has to be more gentle when the big guy runs but it takes up line nicely.
So it's a balance or type of reel and arbour, rod, tippet strenght and expierience on putting them all together to make a successful.
Hope I helped
