The IGFA rules make it hard, and one can compare efforts and catchees with anglers in the past. If that is important, then playing the game could be worth it.
The main dissadvantage is the short shock. It makes leadering a big fish MUCH harder.
I can't really understand people who lobby the IGFA to lower the bar. Poker isn't that much fun when twos and one eyed jacks and black queens are wild.
I have fished both ways, and both are still fun, just different games.
One cast can change your day...maybe your life.
