I'm sure you'll be happy with the retriever.
Two quick tips. You don't have to pull the trigger really hard to retrieve the line. Experiment with different amounts of tension. (if a fish is fighting hard, you'll need lots of tension, to bring inslack line, just a little)
When reeling in line, particularly when you're bringing in a fish, I've found it helps to point the retriever at the fish (so the line comes in straight). Trying to reel in line at a 90degree angle doesn't work too good.
